Use the tool below to convert cream of tartar from the measurements in your recipe to the measurements that you need.
Cream of tartar is a fine white powder left behind in wine barrels during fermentation, used in baking to stabilise egg whites, prevent sugar crystallisation, and activate baking soda. One metric cup (250 ml) of cream of tartar weighs around 200 grams or 7.05 ounces. Most recipes call for it by the teaspoon, where 1 tsp weighs about 4 grams.
Cream of tartar is potent in small amounts. Even a quarter teaspoon makes a measurable difference to a meringue. Measuring by weight avoids the over-packing that comes with scooping, keeping results consistent.

Frequently Asked Questions
- Are cream of tartar and potassium bitartrate the same thing?
- Yes. Potassium bitartrate is another name for cream of tartar, so they are the same ingredient and measure identically. A teaspoon of cream of tartar weighs 4 grams under either name, and every conversion on this page holds whichever name your recipe uses. Recipes swap the two freely, so you can follow either without changing quantities or weighing any differently.
- How much is a pinch of cream of tartar?
- A pinch of cream of tartar is about 0.25 grams, 0.01 ounces, or 0.06 teaspoons, taking a pinch as one sixteenth of a teaspoon (about 0.3 ml). A pinch is not a standard measure and varies between cooks, with some using closer to 1/8 teaspoon. For seasoning it is to taste, but weigh small amounts when a bake has to rise or set.
- What is 100g of cream of tartar in ounces?
- 100 grams of cream of tartar is 3.53 ounces. This is the same for any ingredient, since grams and ounces are both weight units and do not change with what you are weighing. 200 grams is 7.05 ounces and 50 grams is 1.76 ounces. Use the weight converter to switch between grams, ounces, pounds, and kilograms for any amount. Open the weight converter
- How much does a teaspoon of cream of tartar weigh?
- 1 teaspoon of cream of tartar in grams is 4 grams. The ratio is fixed, so 2 teaspoons is 8 grams and half a teaspoon is 2 grams. Ingredients like cream of tartar are usually measured by the spoon, so this is the amount most recipes call for. The conversion chart on this page runs through the spoon amounts recipes ask for.
- How much does a tablespoon of cream of tartar weigh?
- 1 tablespoon of cream of tartar in grams is 12 grams. The ratio is fixed, so 2 tablespoons is 24 grams and half a tablespoon is 6 grams. A tablespoon is three teaspoons, so it scales cleanly when a recipe needs a larger spoon amount. The chart above this FAQ carries the rest of the tablespoon amounts.
- How do you measure cream of tartar in teaspoons?
- 15 grams of cream of tartar is 3.75 teaspoons. The conversion works the same in reverse, so you can go from a weight back to spoons. 30 grams is 7.5 teaspoons and 7.5 grams is 1.88 teaspoons. This helps when you weigh on a scale but the recipe lists teaspoons. The chart above turns the rest of the common weights into spoons.
Related to Cream of Tartar
Lemon Juice
Lemon juice provides the same acidity for stabilising meringues and whipped cream. It adds a faint citrus note, so it works best when that flavour suits the recipe. See our Lemon Juice converter.
White Vinegar
White vinegar is a neutral-flavoured acid that swaps in wherever lemon tang would be unwanted, such as plain meringues and snickerdoodles. Use the same 2:1 ratio as lemon juice. See our White Vinegar converter.
Baking Powder
This swap applies when a recipe uses cream of tartar and baking soda together as a leavening duo. Baking powder already contains both an acid and a base, so the pair can be replaced with 1.5 tsp baking powder. See our Baking Powder converter.
Baking Soda (Bicarb)
Cream of tartar is often paired with baking soda to create a leavening reaction. The baking soda converter covers gram and teaspoon conversions for the other half of the duo. See our Baking Soda (Bicarb) converter.
