How to convert cooking measurements
- Enter the amount from your recipe. Fractions work as you'd write them: 3/4, 1 1/2 or ½.
- Choose the unit you have and the unit you want. Swap exchanges them.
- To go between cups or spoons and grams or ounces, use the third calculator and choose the ingredient, because a cup of flour weighs much less than a cup of honey.
Volume-to-volume and weight-to-weight conversions are exact, because every unit is defined exactly: a US cup is 236.5882365 mL and a pound is 453.59237 g. Converting between volume and weight depends on the ingredient, so those results are close estimates.
US, metric and UK measures
American recipes use US cups (about 237 mL) and US fluid ounces. Nutrition labels in the US round these to 240 mL per cup and 30 mL per fluid ounce. Recipes from Australia, New Zealand, Canada and the UK usually use metric cups of 250 mL, tablespoons of 15 mL and teaspoons of 5 mL. A UK pint is 20 UK fluid ounces, about 568 mL, compared with 473 mL for a US pint.
1 US tablespoon = 3 teaspoons = 1/2 fl oz 1 US cup = 16 tablespoons = 8 fl oz = 236.5882365 mL 1 US quart = 2 pints = 4 cups 1 US gallon = 4 quarts = 128 fl oz = 3.785411784 L 1 pound = 16 ounces = 453.59237 g
Cups to grams
The weight of a cup depends on the ingredient and on how it is measured. The calculator uses the household weights published by the US Department of Agriculture in its FoodData Central database, and shows which one it used. For example, a cup of all-purpose flour is 125 g, a cup of granulated sugar 200 g, a packed cup of brown sugar 220 g but a loose cup only 145 g, and a cup of butter 227 g.
A few ingredients use other sources, named in the result. Type 00 flour, which USDA doesn't measure by the cup, uses King Arthur Baking's published 116 g per cup. Spice blends vary too much for one figure, so curry powder, chili powder, pumpkin pie spice and poultry seasoning are listed separately (from 4.4 g to 8 g per tablespoon). Cake mix, vitamin powder and hydrated yeast have no reliable cup weight at all, so for those the calculator asks for your own density and explains why.
Flour scooped straight from the bag can weigh 10 to 20 percent more than spooned and levelled flour, so for baking, weighing is the most reliable. If your ingredient isn't listed, or you know its density, choose Other and enter it in grams per milliliter or another unit.

Questions
How many tablespoons are in a cup?
16 US tablespoons, or 48 teaspoons. A metric cup of 250 mL holds about 16.9 US tablespoons.
How many grams are in a cup of flour?
About 125 g of all-purpose flour, using the USDA household measure. Bread flour is heavier, about 137 g, and a cup of flour that has been scooped rather than spooned can weigh more.
Is a UK pint the same as a US pint?
No. A UK (imperial) pint is 568.26125 mL and a US pint is 473.176473 mL, so a UK pint is about 20 percent larger.

Limitations
- Volume-to-weight results depend on how the ingredient is measured (spooned, scooped, sifted, packed, chopped); USDA household weights are averages and a scooped cup of flour can weigh 10-20% more than the listed value.
- One density is used per ingredient option; variants not listed (e.g. dark rye flour, kosher salt, sliced almonds) need the custom density.
- Imperial cup, tablespoon and teaspoon are not offered because they have no single statutory definition; UK recipes normally use metric 250/15/5 mL measures, which are offered.
- The US dry pint and dry quart are not offered; pints and quarts are US liquid measures.
- Temperature effects on density (e.g. melted versus solid butter) are not modelled.
