3/4 Cup Ketchup in Grams
Weighing 3/4 cup of ketchup gives you 180 g — the USDA value for a spooned and levelled measure, where a full cup weighs 240 g. Sweet tomato condiment. Everything on this page is approximate by design, so when a recipe matters, confirm the weight on a kitchen scale.

The tablespoon column shows how many tablespoons each amount equals: 3/4 cup is 12 tablespoons, and one tablespoon of ketchup weighs about 15. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 3/4 cup row outwards: every other row is a multiple of 180 g, so scaling a recipe up or down is simple multiplication.
When 3/4 cup shows up in real recipes
Recipes call for 3/4 cup of ketchup more often than people expect, because recipe writers love it as a scaling step: it is the amount you get when you halve one and a half cups, or when you scale a four-serving recipe down to three. That means it appears in scaled recipes, in half-batches and in recipes written for a particular tin size — exactly the situations where the rest of the recipe has also been scaled and the margins are thin. Knowing that 3/4 cup is 180 g lets you scale the whole recipe in grams, which is the only way to keep every ingredient in proportion.
How the weight was measured
Spooned and levelled means the ingredient is measured the way USDA measures it: spooned and levelled. For ketchup, that gives 240 g per cup, and three quarters of a cup of that is 180 g. The source for the figure is USDA, and the confidence in the value is medium. USDA 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.
Worked examples
A small batch built around 3/4 cup
Sometimes 3/4 cup is the whole point of the recipe, not a fraction of it. A small batch of a dipping sauce for a party platter for two people often needs just 3/4 cup of ketchup — 180 g — alongside the other ingredients, and at that scale there is nothing to hide behind: too much and the result is heavy or overpowering, too little and it is bland or falls apart. Weigh the 180 g first, before you start mixing, so you know the foundation is right. Once you know that 3/4 cup is 180 g, you can scale the same recipe up for four people by doubling to 360 g without ever touching a measuring cup, and the result will taste the same.
Doubling and halving from 3/4 cup
Halving a recipe is where 3/4 cup appears most often in real kitchens. A recipe written for a family might call for 1 1/2 cups of ketchup; halved, that is 3/4 cup, or 180 g. The trap is halving by volume: half of 1 1/2 cups is easy to say and hard to measure, because few cup sets have a 3/4-cup measure and fewer still have a 1/3-cup one. Weighing 180 g sidesteps the problem entirely. And if you are doubling instead, two lots of 3/4 cup is 1 1/2 cups, which is 360 g — again, one number on the scale, no cup juggling, and the recipe stays in proportion.
Scaling a recipe that calls for 3/4 cup
A recipe for a marinade for grilled chicken calls for 3/4 cup of ketchup, and you want to make one and a half times as much for guests. On the scale that is simple: 180 g times 1.5 is 270 g, and you weigh it straight into the bowl. Doing the same sum in cups means measuring a cup and an eighth, which no measuring cup marks, so most people guess — and guessing is how a good recipe goes wrong. The same logic works in reverse: halve the recipe and you need 90 g, which is 90 g on the scale and a fiddly 6 tablespoons by volume. ketchup is used for dipping, burgers, glazes and sauces, and the weighed amount keeps the ratio right at any scale.
Practical guidance for ketchup
Sauces and condiments are liquids and pastes, so they are measured by pouring or spooning into a cup — and the thickness of the product decides how accurate that is. A thin sauce levels itself; a thick paste like tomato paste holds peaks and traps air, so the same cup can vary by several grams depending on how it was filled. The figure here, 240 per cup measured spooned and levelled according to USDA, is the standard reference value, but for a sauce that makes or breaks a dish, weigh it: tare the bowl, spoon or pour in 180, and there is no argument. Keep in mind that opened jars and bottles lose moisture slowly in the fridge, so a sauce measured from a jar that has been open for a month may be slightly thicker and heavier per cup than a fresh one — another small reason the scale wins.
Scaling 3/4 cup up and down
Once you know that 3/4 cup of ketchup is 180 g, the rest is arithmetic. A full cup is 240 g, half a cup is 120 g, and two cups is 480 g. Doubling a recipe that calls for 3/4 cup means weighing 360 g; halving it means 90 g, which is about 6 tablespoons. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 180 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with ketchup
- Scooping the cup from the bag. Scooping packs the ingredient down and can add several grams per cup. Always spoon and level, or weigh 180 g.
- Measuring thick paste like a liquid. Tomato paste and mayonnaise hold peaks and trap air; spoon them in and level, or weigh 180 directly.
- Measuring over the mixing bowl. Levelling over the bowl drops the excess straight into the batter, so you have added ketchup you did not intend. Level over the bag or the sink.
- Using a liquid jug. A jug has no straight edge to level against, so pastes measured in one are a guess.
Storage and handling
Refrigerate after opening; use within 6 months. Keeping ketchup 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 bag 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. Label the container with the conversion — 3/4 cup is 180 g — and the next person to bake with it will thank you.
Frequently asked questions
How many grams is 3/4 cup of ketchup?
3/4 cup of ketchup weighs 180 g, measured spooned and levelled according to USDA. That is three quarters of a cup of the full-cup weight of 240 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 3/4 cup of ketchup?
There are 12 tablespoons in 3/4 cup, whatever the ingredient. One tablespoon of ketchup weighs about 15, so 12 tablespoons come to about 180 g. For amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 3/4 cup of ketchup without a scale?
Ketchup is measured spooned and levelled, according to USDA. Spoon it into a 3/4 cup measure, level the top with the back of a knife, and you will be close to 180 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good ingredients and removes the guesswork from every recipe, not just this one.
What is ketchup used for?
Dipping, burgers, glazes and sauces. Sweet tomato condiment. 3/4 cup — 180 g — is a common amount in small batches and scaled recipes, which is why this conversion comes up so often.
How should I store ketchup?
Refrigerate after opening; use within 6 months. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
Can I scale a recipe that uses 3/4 cup of ketchup?
Yes — convert to grams first, then multiply. 3/4 cup is 180 g, a full cup is 240 g, and two cups is 480 g, so doubling means 360 g and halving means 90 g. Scaling by weight keeps every ingredient in proportion, while scaling by volume compounds the error on each one.
