If a recipe calls for a cup of eggs and your measuring jug is marked in millilitres, the answer you need is simple — but only half of it is simple. The volume is fixed: 1 US cup is 236.6 ml, whatever you put in it. The weight is not fixed at all, and that is where most kitchen mistakes happen. One cup of eggs weighs about 243 g, measured poured according to USDA, and that single number is the key to converting the recipe accurately, scaling it up or down, and knowing whether the amount in your bowl is actually the amount the recipe intended. This page gives you both numbers, the full cups-to-millilitres table, worked examples from real recipes, and the measuring method behind the figures, so you can stop guessing and start weighing.
How much is 1 cup of eggs in millilitres?
1 cup of eggs is 236.6 ml and weighs about 243 g. The millilitre figure is exact, because a US cup is defined as 236.6 ml: fill any cup measure to the brim with any ingredient and you have 236.6 ml of it. The gram figure is approximate, because it depends on the density of eggs and on how the cup was filled. The value we use, 243 g, comes from USDA, measured poured, and we use it with medium confidence. If you are baking, scaling a recipe, or cooking for someone with a dietary restriction, weigh the eggs on a kitchen scale and use the gram figure — it is the only measurement that does not depend on how fluffy, damp or tightly packed the ingredient happens to be today.
That distinction between exact volume and approximate weight is the single most useful thing to understand about cup conversions. Recipes written in cups assume a standard cup and a standard technique, and when either of those assumptions breaks, the recipe breaks with it. A cup of eggs scooped straight from the bag can weigh noticeably more than a cup spooned in gently, and the difference is invisible until the finished dish tells you about it. The table below gives you both figures for every amount you are likely to need, so you can convert in either direction without doing the arithmetic yourself.
Cups to millilitres table for eggs
| Cups | Millilitres | Grams (approx.) |
|---|---|---|
| ¼ cup | 59.2 ml | 61 g |
| ⅓ cup | 78.9 ml | 81 g |
| ½ cup | 118.3 ml | 122 g |
| ⅔ cup | 157.7 ml | 162 g |
| ¾ cup | 177.5 ml | 182 g |
| 1 cup | 236.6 ml | 243 g |
| 2 cups | 473.2 ml | 486 g |
| 3 cups | 709.8 ml | 729 g |
| 4 cups | 946.4 ml | 972 g |
Every row in this table follows the same two rules. The millilitre column is the cup fraction multiplied by 236.6 ml, so a quarter cup is 59.2 ml, a third of a cup is 78.9 ml, half a cup is 118.3 ml, two-thirds is 157.7 ml, and three-quarters is 177.5 ml. Those numbers are exact to one decimal place and they are the same for every ingredient on this site. The gram column is the same fraction multiplied by 243 g, the weight of a full cup of eggs, and those numbers are approximate: a quarter cup is about 61 g, half a cup about 122 g, and four cups about 972 g. Use the millilitres when you are measuring volume, and the grams when you are measuring weight — and remember that only the grams need a scale to check.
There is one more conversion worth knowing. One US cup is 8 US fluid ounces, so 1 cup of eggs is also 8 fl oz by volume — but fluid ounces are a volume measure, not a weight measure, and eggs does not weigh 8 ounces. Do not confuse the two: 8 fl oz of eggs is a volume of 236.6 ml, while the weight is about 243 g. If a recipe gives ounces and you are not sure which kind it means, check whether it is talking about a measuring jug (fluid ounces, volume) or a scale (ounces, weight). When a recipe is ambiguous, the gram figure on this page is the safer one to follow.
Worked examples
A sponge cake that needs a cup of eggs
A sponge cake that calls for 1 cup of beaten eggs needs 236.6 ml, about 243 g — roughly five large eggs. Crack them into a jug, beat them lightly, and pour to the 236.6 ml mark at eye level. Bring the eggs to room temperature first: cold eggs do not whip to the same volume, and a sponge depends on that volume.
A quiche that needs half a cup
A small quiche that uses ½ cup of beaten eggs needs 118.3 ml, about 122 g — about two and a half large eggs. In practice, use three eggs and hold back a spoonful, or use two eggs and add a spoonful of cream: the exact figure matters less than the ratio of egg to dairy in the filling, and either route lands close enough.
A big batch of scrambled eggs
A breakfast for a crowd that needs 2 cups of beaten eggs needs 473.2 ml, about 486 g — about ten large eggs. Crack them into a large jug, beat them with a pinch of salt, and pour the amount you need. Weighing is unnecessary at this scale, but the cup figure tells you how many eggs to crack before you start, which is the part that saves time.
How to measure 1 cup of eggs
Eggs are unusual on this page because they are a liquid measured by volume, and the number that matters most is not the cup figure at all — it is the weight of a single egg. A large egg weighs about 50 g, and a cup of lightly beaten eggs, 243 g poured, holds roughly five of them. That is the conversion to remember when a recipe calls for a cup of eggs and you are standing in front of a carton: crack five large eggs, beat them lightly, and you have your cup. The poured method is the right one here because eggs are a liquid — there is nothing to spoon or level. Pour the beaten eggs into a liquid measuring jug, read the level at eye height, and you have 236.6 ml. If the eggs are different sizes, count by weight instead: five large eggs at about 50 g each give you about 250 g, close to the 243 g in the table, and the small difference is well within what any recipe can absorb.
The method behind our figure is poured, and the source is USDA. In practice that means: take a dry measuring cup, spoon the eggs in until it heaps above the rim, then sweep a straight edge — the back of a knife is ideal — across the top to level it. Do not scoop the cup through the ingredient, do not tap the cup on the bench to settle the contents, and do not press the ingredient down. Each of those shortcuts packs more into the cup and makes the weight higher than the 243 g in the table, sometimes by a surprising amount. For a liquid or a pourable ingredient the method is simpler: pour into a liquid measuring jug, set it on a flat surface, and read the level at eye height.
If you do not have a scale, the spooned-and-levelled cup is the best you can do, and for most everyday cooking it is good enough. But if the recipe is a bake, a preserve, or anything where the ratio of ingredients does the structural work, borrow or buy a scale: even a basic digital scale is more accurate than the best cup technique, and it is faster once you are used to it. Put the bowl on the scale, press tare, and add eggs until the display reads the grams you need. That is the whole technique, and it removes the single biggest source of variation in cup-based recipes.
Working with eggs by the cup
Eggs is used for baking, custards, omelettes and binding. Whole raw eggs, lightly beaten; one large egg is about 50 g.
Count eggs, weigh when it matters
Refrigerate in the carton; use by the date on the box. For most cooking, counting large eggs is enough: about five large eggs make a cup. For baking, where the egg is doing structural work, weighing is better — crack the eggs into a bowl on the scale and use 243 g for a cup. If a recipe calls for a number of eggs rather than a cup, use the count; if it calls for a cup, use the weight. The two routes agree closely enough that either works, but the weight is the more repeatable of the two.
Room temperature eggs mix better
Cold eggs straight from the fridge do not emulsify as well into batters, and they can seize melted butter. If a recipe calls for a cup of eggs, bring them to room temperature first by sitting them in warm water for ten minutes. It is a small step that makes a visible difference to the texture of the finished bake.
Common mistakes with cups and millilitres
The most common mistake is treating the millilitre figure and the gram figure as interchangeable. They are not: 236.6 ml is a volume and 243 g is a weight, and the only ingredient for which they are equal is water, where 1 ml weighs 1 g. For eggs, 236.6 ml weighs about 243 g, and if you weigh out 236.6 g of eggs instead of measuring 236.6 ml, you will have the wrong amount — too much if 243 is greater than 236.6, too little if it is less. Always check whether the recipe wants a volume or a weight, and use the matching column of the table.
The second most common mistake is using the wrong cup. A US cup is 236.6 ml, a metric cup is 250 ml, and a UK cup in older recipes can mean something else again. If your measuring cup came with a set that does not say which standard it follows, check it against a measuring jug: fill the cup with water and pour it into the jug. If it reads 236.6 ml, it is a US cup; if it reads 250 ml, it is a metric cup. Once you know, write it on the cup with a permanent marker so you never have to guess again.
The third mistake is measuring over the mixing bowl. It feels efficient, but a spill goes straight into the batter and cannot be taken back, and a cup read from above always looks fuller than it is. Measure over the sink or a plate, level the cup, and then tip it into the bowl. It takes five seconds longer and it prevents the kind of error that ruins a bake.
Frequently asked questions
How many millilitres is 1 cup of eggs?
1 cup of eggs is 236.6 ml. That figure is fixed: a US cup is defined as 236.6 ml, so it is the same for every ingredient. What changes from one ingredient to another is the weight, and 1 cup of eggs weighs about 243 g. The volume never changes; the weight always depends on the ingredient.
How many grams is 1 cup of eggs?
1 cup of eggs weighs about 243 g, measured poured according to USDA. The word "about" matters: the exact weight of a cup depends on how the ingredient is handled, how finely it is ground or cut, and how much moisture it holds. For baking and for any recipe where the amount is critical, weigh the ingredient on a kitchen scale rather than trusting the cup.
Is 1 cup of eggs the same as 250 ml?
No. A US cup is 236.6 ml, while a metric cup — used in Australia and in many metric recipes — is 250 ml. The difference is 13.4 ml per cup, which is about 5.7%. If your recipe was written with metric cups and you measure with a US cup, you will be short on every cup; if it was written with US cups and you use a metric cup, you will be over. Check which cup your recipe means, and when in doubt use the gram figure, 243 g, which does not depend on the cup at all.
How many tablespoons of eggs are in a cup?
There are 16 tablespoons in 1 cup, so 1 cup of eggs is 16 tablespoons, weighing about 243 g in total. One tablespoon is about 15.2 g and one teaspoon is about 5.1 g. These spoon figures are worked back from the cup weight, so they carry the same approximation — they are useful for small amounts, but for a full cup the scale is still the more accurate tool.
How many eggs are in 1 cup?
About five large eggs. A large egg weighs about 50 g, and 1 cup of lightly beaten eggs weighs about 243 g, so five eggs land very close to a cup. If your eggs are medium, you will need about six; if they are extra large, four may be enough. For baking, weigh the beaten eggs rather than counting — 243 g is the target, whatever the size of the eggs in your carton.
Can I use a kitchen scale instead of a cup for eggs?
Yes, and for most recipes you should. Put your bowl on the scale, press tare to zero it, and add eggs until the display reads the grams you need — 243 g for a full cup, 122 g for half a cup, 61 g for a quarter cup. A scale removes every variable that makes cup measuring unreliable: how firmly the ingredient was packed, how it was scooped, and how humid the day is.
Why does the weight of a cup of eggs vary between sources?
Different sources measure differently. Some scoop the cup through the ingredient, some spoon it in, some pack it down, and some use a different variety or a different moisture level. The figure on this page, 243 g, comes from USDA using the poured method, which is the most repeatable way to fill a cup. If another source gives a different number, it is usually because the method was different — not because one of them is wrong.
