OmniCalcsCooking Unit Converter
Convert cooking measurements — cups, grams, ounces, teaspoons and milliliters — for the exact ingredient you're using.
How to Use This Converter
Choose the ingredient (or a custom density), type an amount, and pick the unit to convert from. Every other unit updates at once.
- Use "Custom density" to add any ingredient's grams per milliliter.
- Pick the right ingredient — flour and sugar have very different weights per cup.
- Convert from grams or ounces to cups for US recipes, or the reverse.
Frequently Asked Questions
Why is a cup of flour lighter than a cup of sugar?
Flour is fluffy and less dense. One cup of all-purpose flour weighs about 125 g, while one cup of granulated sugar weighs about 200 g.
Are cups the same everywhere?
No — the US cup is 237 ml, but the metric cup used in Australia and New Zealand is 250 ml. This tool uses the US standard.
Should I weigh or measure by volume?
For baking, weighing in grams is far more accurate. A kitchen scale removes the variation from scooping flour.
How do I convert tablespoons to grams?
Multiply the ingredient's grams-per-cup by 1/16. For butter, 1 tbsp = 14.2 g.
Practical Example
A recipe calls for 2 cups of flour, but your scale only shows grams:
- 2 cups × 125 g/cup = 250 g
- In ounces: 250 g ÷ 28.35 = 8.8 oz
- In tablespoons: 2 × 16 = 32 tbsp
What Your Results Mean
- Volume units (cups, tbsp, tsp, ml) — measure space; ideal for liquids and scooping.
- Weight units (g, oz) — measure mass; the reliable choice for baking.
- Ingredient density — the bridge between the two, in grams per milliliter.
