How to Use the Cooking Converter
Select an ingredient from the dropdown, enter the amount, and choose the from/to units (cups, grams, tablespoons, teaspoons, mL, oz). If your ingredient is not in the list, use the manual density input mode.
Cooking Converter Formula
grams = cups × grams_per_cup; grams = tbsp × grams_per_tbsp1 cup= 16 tbsp = 48 tsp = 240 mL

2 × 120g/cup
240 grams
Why Cups Are the Problem, Not the Solution
Most recipes online are written in American cups, but a cup is a measure of volume — and volume is a terrible way to measure dry ingredients. A cup of flour can weigh anywhere from 120 to 150 grams depending on whether it was scooped, spooned, or packed. That 25% swing is the difference between a tender cake and a dense one. This is why professional bakers weigh everything in grams: weight is exact, volume is a guess. The most reliable thing you can do is convert a recipe to grams once and use a kitchen scale.
Common Conversions Worth Memorising
A few weights cover most baking. Note that they differ by ingredient — a cup of flour and a cup of sugar are not the same weight, because the grains pack differently.
- All-purpose flour: 1 cup ≈ 120 g.
- Granulated sugar: 1 cup ≈ 200 g.
- Brown sugar (packed): 1 cup ≈ 220 g.
- Butter: 1 cup ≈ 227 g (and 1 stick ≈ 113 g).
- Volume constants: 1 cup = 16 tbsp = 240 mL; 1 tbsp = 3 tsp = 15 mL.
The Indian Kitchen Note
Indian cooks face an extra trap: the "cup" in Indian recipes and the standard measuring cup are often different. Many Indian recipes assume a 200 mL cup (and sometimes a tea-cup smaller still), while US recipes use a 240 mL cup. Using the wrong one throws ratios off by 20%, which matters most in baking and in rice-to-water ratios. When a recipe does not specify, weigh in grams if you can, or check whether the source is Indian (often ~200 mL) or American (240 mL) before trusting the cup.
Liquids, and When Volume Is Fine
Volume measurement is genuinely fine for liquids — water, milk, and oil have consistent density, so a cup of water is reliably about 240 mL. The precision problem is specific to dry and compressible ingredients like flour, powdered sugar, cocoa, and brown sugar. A practical rule: measure liquids by volume, measure flour and sugar by weight, and reserve teaspoons and tablespoons for small quantities of salt, baking powder, and spices where a few grams either way will not break the dish. Use this converter to translate any recipe into the units your kitchen is set up for.
Frequently Asked Questions
How many grams in a cup of flour?
One cup of all-purpose flour = 120 grams. One cup of bread flour = 127 grams. One cup of whole wheat flour = 113 grams. Weights vary by flour type and how it is measured (scooped vs spooned).
How many grams in a cup of sugar?
One cup of granulated white sugar = 200 grams. One cup of powdered/icing sugar = 120 grams. One cup of packed brown sugar = 220 grams.
How many tablespoons in a cup?
1 cup = 16 tablespoons = 48 teaspoons = 240 mL. This is the standard US measurement used in most English-language recipes.
