Why weight beats volume
Cups measure volume; grams measure mass. For water the two agree (1 US cup = 236.6 g), but for almost everything else they don't: 1 cup of all-purpose flour is 120 g, 1 cup of honey is 336 g, and 1 cup of table salt is 288 g. A recipe that says "1 cup" is really saying "however much of this ingredient fills 236.6 mL" — and how much that weighs depends on the ingredient's density and how you fill the cup.
That is why professional bakers weigh ingredients. The spoon-and-level method (spoon flour into the cup, level with a knife) gives 120 g per cup — the King Arthur Baking standard used in this calculator's database. Scooping the cup straight from the bag packs in about 140 g instead, a 17% error that turns tender cake into dry brick. Salt is even trickier: a tablespoon of table salt weighs 18 g, but a tablespoon of Diamond Crystal kosher salt weighs only 8 g, because the crystals are hollow pyramids. Same spoon, 2.25× the salt.
Brown sugar adds another wrinkle: recipes mean packed brown sugar (213 g per cup), while granulated sugar is 198 g and unsifted powdered sugar just 113 g. And cups themselves are not universal: a US cup is 236.588 mL, a metric cup is 250 mL, and an imperial cup is 284.131 mL. This calculator keeps all of it straight — pick your ingredient and your cup, and get the honest gram weight.
How to use this calculator
Volume tab converts between teaspoons, tablespoons, fluid ounces, US / metric / imperial cups, pints, quarts, milliliters, deciliters and liters — with kitchen fractions like 3/8 cup shown automatically. The quick chips answer the most-searched questions in one tap. Ingredient tab converts any of the 88 database ingredients between volume and weight (grams and ounces), using published per-cup weights. Butter / oven / scale tab converts butter between sticks, cups, tablespoons, grams and ounces; converts oven temperatures between °F, °C and gas marks; and scales any amount by ½×, 2×, 3× or a custom factor.

Worked examples
Example 1 — how many cups is 6 tablespoons?
Question: a recipe calls for 6 tablespoons of olive oil, but your measuring cup only shows cups.
- Convert to milliliters: 6 tbsp × 14.78676478125 mL = 88.7206 mL.
- Convert to US cups: 88.7206 mL ÷ 236.5882365 mL = 0.375 cup.
6 tablespoons = 3/8 cup (0.375 cup)
Example 2 — 2 cups of flour in grams
Question: a European recipe needs 2 cups of all-purpose flour in grams.
- Look up the ingredient: 1 US cup all-purpose flour = 120 g (King Arthur Baking).
- Multiply: 2 × 120 g = 240 g.
- In ounces: 240 g ÷ 28.349523125 = 8.4658 oz.
2 cups all-purpose flour = 240 g (8.4658 oz)
Example 3 — butter sticks and oven temperature
Question: a US recipe needs 1 stick of butter and a 350°F oven.
- Butter: 1 stick = 4 oz exactly = 4 × 28.349523125 g = 113.3981 g = 8 tbsp.
- Oven: (350 − 32) × 5/9 = 176.67 °C.
- Gas mark lookup: 350°F → gas mark 4.
1 stick = 113.3981 g = 8 tbsp; 350°F = 176.67°C (gas mark 4)
Practical tips
- Spoon and level flour. Never scoop the cup through the bag. Spoon flour loosely into the cup and level it — that is the 120 g this calculator assumes.
- Pack brown sugar, sift nothing else. Brown sugar is measured packed (213 g/cup); powdered sugar in this database is unsifted (113 g/cup). Sifting removes about 10% of the weight.
- Weigh salt by type. 1 tablespoon of table salt (18 g) is not 1 tablespoon of Diamond Crystal kosher (8 g). When a recipe just says "salt", assume table salt unless it specifies.
- Melted vs solid butter weighs the same. Melting changes volume slightly but not mass: 1 stick is 113.4 g either way. Measure by weight when precision matters.
- Oil the spoon for honey. A teaspoon of oil on the measure lets honey and molasses slide out completely — otherwise up to 10% stays behind.
- Trust a thermometer, not the dial. Home ovens routinely run 25°F off. Gas marks are conventional equivalents; the °F/°C math is exact.
- Don't scale leavening blindly. Doubling a cake? Start with 1.5× baking powder and adjust — chemical leaveners don't scale linearly with batter volume.
- Australian tablespoons are 20 mL. If a recipe is Australian, convert via milliliters instead of tablespoons — their tablespoon is 35% bigger than the US one.

Frequently asked questions
How many cups is 6 tablespoons?
6 tablespoons = 0.375 cup, written 3/8 cup. The math: 1 US cup = 16 tablespoons, so 6 / 16 = 0.375. The kitchen ladder to memorize: 1 tbsp = 3 tsp; 1/8 cup = 2 tbsp; 1/4 cup = 4 tbsp; 1/3 cup = 5 tbsp + 1 tsp; 1/2 cup = 8 tbsp; 1 cup = 16 tbsp.
How many tablespoons are in 1/8 cup?
Exactly 2 tablespoons. Since 1 cup = 16 tablespoons, 1/8 cup = 16 / 8 = 2 tbsp. Use the Volume tab above to convert any fraction of a cup instantly.
How many tablespoons are in 1/4 cup?
Exactly 4 tablespoons. 1/4 cup x 16 tbsp per cup = 4 tbsp. If a recipe calls for 1/4 cup of oil and you only have a tablespoon measure, scoop 4 level tablespoons.
How many teaspoons is 5 mL?
5 mL = 1 metric teaspoon exactly, and 1.01 US teaspoons (a US tsp is 4.929 mL). For cooking the difference is negligible; medicine droppers treat 5 mL as 1 tsp. Five milliliters is also 1/3 of a US tablespoon.
How many grams are in 1 cup of all-purpose flour?
120 grams, when measured by the spoon-and-level method (the King Arthur Baking standard this calculator uses). If you scoop directly from the bag you can pack in about 140 g - a 17% error that makes cakes tough and dry. A kitchen scale removes the guesswork entirely.
How many grams are in 1 cup of sugar?
It depends on the sugar: granulated white sugar = 198 g per cup, brown sugar packed = 213 g per cup, confectioners' (powdered) sugar unsifted = 113 g per cup. Same cup, very different weights - this is exactly why professional recipes list grams.
How many grams are in a stick of butter?
1 US stick of butter = 113.4 g = 4 oz = 8 tablespoons = 1/2 cup. Two sticks make 1 cup (226.8 g). European-style blocks are usually 250 g, so check the wrapper before assuming sticks.
What is the difference between a US cup and a metric cup?
A US legal cup is 236.588 mL, a metric cup (Australia, Canada) is 250 mL, and a UK imperial cup is 284.131 mL. A '1 cup flour' recipe from Sydney is about 6% larger than one from Chicago. This converter defaults to the US cup and lets you switch.
What is gas mark 4 in Fahrenheit and Celsius?
Gas mark 4 = 350 F = 175 C (176.7 C by exact formula). The common marks: 1 = 275 F / 140 C, 2 = 300 F / 150 C, 3 = 325 F / 165 C, 4 = 350 F / 175 C, 5 = 375 F / 190 C, 6 = 400 F / 200 C, 7 = 425 F / 220 C, 8 = 450 F / 230 C, 9 = 475 F / 240 C. Gas marks are conventional equivalents, so trust your oven thermometer for the final word.
How do I scale a recipe up or down?
Multiply every amount by the factor: 2 cups flour at 2x becomes 4 cups (480 g). Use the Recipe Scaling section above for quick 1/2x, 2x and 3x factors. One caveat: leavening, salt, yeast and strong spices often should not scale perfectly linearly - for a doubled cake, start with 1.5x baking powder and adjust. For full multi-ingredient smart scaling, use our recipe-scaler tool.
Why does a cup of flour weigh different amounts in different charts?
Two reasons: flour type and measuring method. All-purpose is 120 g/cup, whole wheat 113 g, cake flour 120 g (King Arthur chart) - and the dip-and-sweep method packs about 20 g more per cup than spoon-and-level. Charts disagree because they assume different methods. Weighing in grams ends the argument.
Is a tablespoon the same size everywhere?
No. US and Canada: 14.787 mL. UK and most metric countries: 15 mL. Australia: 20 mL - an Australian tablespoon is 35% bigger than a US one. This converter uses the US tablespoon (14.78676478125 mL); for Australian recipes, convert via milliliters instead.
How many ounces are in a cup?
8 fluid ounces - that is volume. Weight ounces depend on the ingredient: 1 cup of water weighs 8.35 oz (236.6 g) but 1 cup of flour weighs only 4.23 oz (120 g). Never assume 8 oz = 1 cup for dry ingredients.
