How to Convert Cooking Measurements: Cups to Grams, Tablespoons to Milliliters, and More

Feb 1, 2025

Cooking is both an art and a science. While creativity takes center stage, accurate measurements are essential to get perfect results—especially when baking or trying new recipes. But what happens when a recipe calls for "1 cup of flour," and you only have a kitchen scale? Or when a British recipe uses grams, but you're working with cups and teaspoons? Understanding how to convert cooking measurements can save the day.

In this guide, we’ll break down common cooking measurement conversions, such as cups to grams, tablespoons to milliliters, and more. Whether you’re a seasoned chef or a home cook exploring new recipes, these tips will make navigating cooking measurements a breeze.

Why Cooking Conversions Matter

Recipes come from all over the world, and different regions use different measurement systems. For example:

  • The United States primarily uses cups, tablespoons, and teaspoons.
  • Most other countries use the metric system, relying on grams and milliliters.

Without proper conversions, your dish could turn out too dry, too wet, or simply not work at all. Understanding conversions ensures accuracy and helps you follow recipes from any part of the globe.

Common Cooking Measurement Conversions

Let’s dive straight into some of the most common conversions to help you in the kitchen.

1. Cups to Grams (Dry Ingredients)

Dry ingredients like flour, sugar, and butter vary in weight, so 1 cup doesn’t always equal the same number of grams. Here are some common conversions:

Ingredient1 Cup (US)
All-Purpose Flour120 grams
Sugar (Granulated)200 grams
Brown Sugar (Packed)220 grams
Butter227 grams

Tip: Always spoon dry ingredients into the measuring cup and level it off with a knife for accuracy.

2. Cups to Milliliters (Liquid Ingredients)

Liquid ingredients are easier to convert because 1 cup is always equal to 240 milliliters (ml) in the US measurement system. Here’s a quick reference:

Liquid1 Cup (US)
Water240 ml
Milk240 ml
Oil240 ml

For smaller amounts:

  • 1 tablespoon = 15 ml
  • 1 teaspoon = 5 ml

3. Tablespoons to Milliliters

Tablespoons and teaspoons are common for measuring smaller amounts of both dry and liquid ingredients. Here’s a quick conversion:

MeasurementMilliliters
1 tablespoon (US)15 ml
1 teaspoon (US)5 ml

Pro Tip: If you’re doubling or halving a recipe, keeping these conversions in mind can help scale your ingredients accurately.

4. Ounces to Grams

Sometimes recipes measure ingredients in ounces instead of grams. Here’s how to convert:

  • 1 ounce (oz) = 28.35 grams

For example:

  • 8 ounces (1 cup of shredded cheese) = about 227 grams

5. Temperature Conversions: Fahrenheit to Celsius

If you’re following an international recipe, you may need to convert oven temperatures. Here’s a simple formula:

Celsius = (Fahrenheit - 32) × 5/9

Or use this quick reference:

Fahrenheit (°F)Celsius (°C)
350°F175°C
400°F200°C
450°F230°C

Handy Tools for Cooking Conversions

While memorizing conversions can be helpful, using tools like kitchen scales, measuring cups, and conversion charts can make your life much easier. Here are some must-haves:

  1. Digital Kitchen Scale: Perfect for measuring dry ingredients in grams for precision.
  2. Measuring Cups and Spoons: Essential for recipes using cups, tablespoons, and teaspoons.
  3. Unit Conversion Apps or Web Tools: Tools like our unit conversion web app can quickly convert cups to grams, tablespoons to milliliters, and more, so you can focus on cooking.
