Can I convert a volume to a weight (cups to grams)?

Not with this tool — that conversion depends on the density of the ingredient. Flour, sugar, and butter all weigh differently per cup. For ingredient-specific conversions, use a recipe conversion chart.

Are these US cups or metric cups?

US customary cups (236.588 mL). Metric cups (250 mL, used in Australia and Canada) are slightly larger. For recipes from those countries, note the discrepancy.

How to Convert Cooking Measurements — Cups, Grams, oz Free (2026)

By Rui Barreira · Last updated: 18 June 2026

Cooking recipes use two distinct measurement systems — US customary volume (cups, tablespoons, teaspoons) and metric weight (grams, kilograms) — and they often mix in imperial (ounces, pounds). Converting between them is a constant need when following international recipes or scaling portions.

How to Use

Select Volume or Weight depending on what you are measuring.
Enter your amount and select the source unit.
All conversions appear instantly in a table — no button to click.

How It Works

Each unit is defined relative to a base (millilitres for volume, grams for weight). The tool converts the input to that base, then divides by each target unit's factor. For example: 1 cup = 236.588 mL; 1 tablespoon = 14.787 mL; so 2 cups ÷ 14.787 mL/tbsp = approximately 32 tablespoons.

Volume Reference

The US customary volume system is built on nested ratios: 3 teaspoons = 1 tablespoon; 16 tablespoons = 1 cup; 2 cups = 1 pint; 2 pints = 1 quart; 4 quarts = 1 gallon. Fluid ounces are separate: 8 fl oz = 1 cup. The metric system is simpler — 1000 mL = 1 L.

Weight Reference

The imperial weight system: 16 oz = 1 lb. Metric: 1000 g = 1 kg. One ounce is approximately 28.35 grams; one pound is approximately 453.59 grams.
