1 Cup Maple Syrup in Millilitres
1 cup of maple syrup is 236.6 ml and weighs 312 g (poured, King Arthur Baking). Syrup boiled from maple tree sap; graded by colour and flavour. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.
If you have ever wondered why a recipe that works with one sugar fails with another, the answer is usually in the cup. Volume stays constant at 236.6 ml per cup, but weight does not, and baking is really a matter of weight. The table below gives you both, so you can measure with a jug or a scale and get the same result.
Why millilitres and grams are two different answers
The reason this page lists two numbers for every amount is that a cup is a unit of volume, not of weight. One US cup holds 236.6 ml of anything, but what that space weighs depends on what fills it. Granulated sugar, brown sugar and powdered sugar all occupy the same 236.6 ml, yet their weights differ by up to 100 g per cup. Packing changes the answer further: a packed cup of brown sugar weighs far more than a loosely filled one. That is why serious bakers weigh sweeteners. The millilitre column tells you what to pour into a jug; the gram column tells you what to put on a scale. Use the one that matches your recipe, and when the recipe matters, use grams.

|---|---|---|---|
| 1/4 cup | 59.1 ml | 78 g | 4 tbsp |
| 1/3 cup | 78.9 ml | 104 g | 5.3 tbsp |
| 1/2 cup | 118.3 ml | 156 g | 8 tbsp |
| 2/3 cup | 157.7 ml | 208 g | 10.7 tbsp |
| 3/4 cup | 177.4 ml | 234 g | 12 tbsp |
| 1 cup | 236.6 ml | 312 g | 16 tbsp |
| 2 cups | 473.2 ml | 624 g | 32 tbsp |
| 3 cups | 709.8 ml | 936 g | 48 tbsp |
| 4 cups | 946.4 ml | 1248 g | 64 tbsp |
The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of maple syrup is about 19.5 g and 14.8 ml, which is handy when a recipe calls for a spoonful rather than a cup: divide the cup weight by 16 and you have the tablespoon weight. Remember that the millilitre column never changes — 1 cup is always 236.6 ml — while the gram column depends on the King Arthur Baking density of 312 g per cup, measured poured. If your recipe was written in grams, read the gram column; if it was written in cups or millilitres, read the millilitre column.
How much is 100 ml, 250 ml and 500 ml of maple syrup?
| Millilitres | Cups | Grams |
|---|---|---|
| 100 ml | 0.4 cups | 131.9 g |
| 250 ml | 1.1 cups | 329.7 g |
| 500 ml | 2.1 cups | 659.3 g |
Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of maple syrup is just over a cup — 1.1 cups — and weighs 329.7 g, while 500 ml is 2.1 cups and 659.3 g. A standard measuring jug usually has both millilitre and cup markings, so you can pour to either scale, but the gram column is the one to use on a scale. Note that 100 ml is 0.4 of a cup, which is why metric recipes rarely line up neatly with cup measures.
Worked examples
Pancakes calling for 2 cups of maple syrup
A pancakes recipe that calls for 2 cups of maple syrup needs 473.2 ml, which weighs 624 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 624 g straight into the bowl. Because maple syrup is used for pancakes, glazes, baking and dressings. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 624 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Glazes calling for half a cup of maple syrup
A glazes recipe that calls for half a cup of maple syrup needs 118.3 ml, which weighs 156 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 156 g straight into the bowl. Because maple syrup is used for pancakes, glazes, baking and dressings. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 156 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Baking calling for 3 cups of maple syrup
A baking recipe that calls for 3 cups of maple syrup needs 709.8 ml, which weighs 936 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 936 g straight into the bowl. Because maple syrup is used for pancakes, glazes, baking and dressings. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 936 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Scaling works the same way in both directions. Double the recipe and 3 cups becomes 1419.6 ml, or 1872 g. Halve it and you need 354.9 ml, or 468 g. When you scale, always scale by weight if the original recipe was written in grams, and by volume if it was written in cups — mixing the two mid-recipe is how scaling errors creep in. And remember that a US cup is 236.6 ml, while a metric cup is 250 ml: if you are following a recipe from Australia, New Zealand or South Africa, one cup means 250 ml, which is 329.7 g of maple syrup, not 312 g. Check which cup your recipe uses before you convert.
How the weight was measured
Poured means the ingredient is poured into a liquid measuring jug and read at eye level at the meniscus, or weighed straight into the bowl on a scale. Liquids settle flat, so a poured cup is far more repeatable than a cup of any dry ingredient.
The source for the 312 g figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
The figure is not disputed in the same way as the flour and sugar conversions: King Arthur Baking lists 312 g per cup, and other reliable sources cluster close to it. Small differences of a gram or two between sources are rounding, not disagreement.
Common mistakes with maple syrup
- Scooping instead of spooning. Dipping the cup into the bag packs the sugar and adds grams the recipe did not ask for. Spoon it in and level it off.
- Packing a sugar that should be spooned. Only brown sugar and muscovado are measured packed. Packing granulated or caster sugar over-measures it by a wide margin.
- Measuring syrups in a dry cup. Sticky syrups cling to a dry cup and never fully reach the bowl. Use a liquid jug, or weigh the syrup straight into the bowl.
- Swapping sugars cup for cup. A cup of honey weighs nearly 70 percent more than a cup of granulated sugar. Swap by weight, and adjust the liquid in the recipe, or the bake will be too wet and too sweet.
Storage and handling
Refrigerate after opening; up to 1 year. Syrup boiled from maple tree sap; graded by colour and flavour. Keeping maple syrup stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a container has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. maple syrup is used for pancakes, glazes, baking and dressings. and it is worth keeping a note of the 312 g per cup figure on the container, so the conversion is always to hand.
Frequently asked questions
How many cups is 250 ml of maple syrup?
250 ml of maple syrup is 1.1 cups, and it weighs 329.7 g. The table above lists 100 ml, 250 ml and 500 ml alongside their cup equivalents, so a recipe written in millilitres converts in one step. For anything more precise, weigh the maple syrup on a kitchen scale.
How many millilitres is 1 cup of maple syrup?
1 cup of maple syrup is 236.6 ml. That is the fixed volume of one US customary cup, and it is the same for every ingredient on this site: the cup does not change, only the weight inside it does. If your recipe is from a metric country, note that a metric cup is 250 ml, which is a different measure — check which cup the recipe means before converting.
How many grams is 1 cup of maple syrup?
1 cup of maple syrup weighs 312 g, measured poured according to King Arthur Baking. That is the figure the conversion table on this page is built on, and it is the value to use when a recipe gives weights. All the gram figures here are approximate, so when a bake really matters, verify with a kitchen scale.
Is 1 cup of maple syrup always 236.6 ml?
Yes, as long as the recipe means a US customary cup. One US cup is 236.6 ml by definition, whatever is in it. The confusion comes from the metric cup, which is 250 ml, and from the old imperial cup. If a recipe does not say which cup it uses, a US recipe almost always means the 236.6 ml cup, while a recipe from Australia or New Zealand usually means the 250 ml metric cup.
How do I measure maple syrup without a scale?
Poured means the ingredient is poured into a liquid measuring jug and read at eye level at the meniscus, or weighed straight into the bowl on a scale. Liquids settle flat, so a poured cup is far more repeatable than a cup of any dry ingredient. That gives the closest result to 312 g per cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
