Kitchen Measurement Conversions Made Easy

March 5, 2025·5 min read

A practical guide to converting cooking measurements — cups to milliliters, ounces to grams, tablespoons to teaspoons, and more.

Recipes from different countries use different measurement systems. An American recipe calls for cups; a British recipe uses grams; a French recipe specifies milliliters. If you cook from international sources — or just bake precisely — you need to speak all three languages.

Volume Conversions

  • 1 cup (US) = 236.6 mL
  • 1 tablespoon = 15 mL
  • 1 teaspoon = 5 mL
  • 1 fluid ounce = 29.6 mL
  • 1 pint (US) = 473 mL
  • 1 liter = 4.23 US cups

Weight Conversions

  • 1 ounce = 28.35 grams
  • 1 pound = 453.6 grams
  • 100 grams ≈ 3.5 ounces
  • 500 grams ≈ 1.1 pounds

Why Weight Beats Volume for Baking

A cup of flour can weigh anywhere from 120 to 160 grams depending on how it's scooped. A cup of packed brown sugar is very different from a loosely measured one. Weight measurements are more precise — which is why professional bakers and most European recipes use grams. A kitchen scale is the best investment a serious baker can make.

Oven Temperature Quick Reference

  • Gas Mark 1 = 275°F = 140°C — very low
  • Gas Mark 4 = 350°F = 180°C — moderate
  • Gas Mark 6 = 400°F = 200°C — hot
  • Gas Mark 9 = 475°F = 245°C — very hot

When baking, always note whether a recipe uses US cups or metric volume. The same word 'cup' means different amounts in Australia (250 mL) vs the US (236.6 mL).
