Cooking Measurements Guide

Volume Measurements

Volume is used to measure liquids and sometimes dry ingredients like flour. Common cooking volume measurements include teaspoons, tablespoons, cups, and liters. The metric system (milliliters) is used internationally and in scientific cooking.

Quick Volume Reference

1 tablespoon = 3 teaspoons = 15 ml
1 cup = 16 tablespoons = 240 ml
1 liter = 4.2 cups = 1000 ml
1 fluid ounce = 30 ml (approximately)

Weight Measurements

Weight is more accurate for baking and some recipes. Grams and ounces are the most common weight measurements. For best results with baking, use weight measurements instead of volume.

Quick Weight Reference

1 ounce = 28.35 grams
1 pound = 16 ounces = 453.6 grams
1 kilogram = 1000 grams = 2.2 pounds

Ingredient-Specific Conversions

Note that volume-to-weight conversions vary by ingredient density. For example, 1 cup of flour weighs about 125g, but 1 cup of sugar weighs about 200g. These conversions are approximate for water and common cooking liquids only.

Scaling Recipes

To scale a recipe, divide the desired portion size by the original portion size, then multiply all ingredient quantities by this factor. For example, to double a recipe that serves 4 and you want to serve 8, multiply all ingredients by 2.

Frequently Asked Questions

Should I use volume or weight for accurate recipes?

Weight is more accurate, especially for baking. Volume measurements can vary depending on how you pack ingredients and the humidity in your kitchen. Many professional bakers and international recipes use weight exclusively.

Why is 1 cup different from 240 ml?

There are actually different types of cups used in cooking. A US legal cup is 240 ml, but a metric cup is 250 ml, and traditional imperial cups are slightly different. Always check your recipe's origin for the intended measurement.

Can I convert dry ingredients using these conversions?

This converter treats most dry ingredients as if they have the same density as water. For more accurate conversions of specific dry ingredients (flour, sugar, etc.), check ingredient-specific conversion charts or use your kitchen scale.

What about old British measurements like drams or gills?

This converter focuses on modern cooking measurements. If you encounter vintage measurements, remember that old British cups, drams, and gills are quite different from modern equivalents and should be looked up separately.
