How to Tell Which Cup a Recipe Uses

How to Convert Cups to Milliliters

✓ The Formula

mL = cups × 236.588

For metric cups: mL = cups × 250

Step-by-Step Examples

Example 1: Convert 2 cups to mL

  1. Start with the amount: 2 cups
  2. Multiply by 236.588: 2 × 236.588 = 473.176 mL
  3. Round if needed: 473 mL or ~475 mL

Example 2: Convert 1/3 cup to mL

  1. Start with the fraction: 1/3 cup = 0.333... cups
  2. Multiply by 236.588: 0.333 × 236.588 = 78.86 mL
  3. Round: 79 mL or ~80 mL

Practical Tips for Using Cups and Milliliters

📏 Get Proper Measuring Tools

Invest in both US measuring cups AND a liquid measuring cup with mL markings. This lets you follow any recipe accurately.

💧 Liquid vs Dry Measuring

Use liquid measuring cups for liquids (water, milk, oil). Use dry measuring cups for dry ingredients (flour, sugar). The measurement is the same in mL, but the technique differs.

🔄 Convert Before You Start

Convert all measurements before starting a recipe. Write them down so you don't have to calculate while cooking.

⚖️ When Precision Matters

For baking (especially bread and pastries), use a kitchen scale and measure in grams instead of cups or mL for best results.

Frequently Asked Questions

How many milliliters in 1 cup?

1 US cup = 236.588 milliliters. This is the standard measurement used in American recipes. However, metric cups (used in Australia, New Zealand, and Canada) are 250 mL. Always check which type of cup a recipe uses.

How many mL in 1/2 cup?

1/2 cup = 118.294 milliliters, commonly rounded to 118 mL or 120 mL. This is exactly half of the standard US cup measurement.

How many mL in 1/4 cup?

1/4 cup = 59.147 milliliters, commonly rounded to 59 mL or 60 mL. This is one quarter of a US cup.

Is a US cup the same as a metric cup?

No. US cup = 236.588 mL while metric cup = 250 mL. The difference is about 13.4 mL (roughly 1 tablespoon). Australian, New Zealand, and Canadian recipes typically use metric cups.

How many cups is 500 mL?

500 mL = 2.11 US cups, which is approximately 2 cups plus 2 tablespoons. For metric cups: 500 mL = 2 metric cups exactly.

How many cups in 1 liter?

1 liter (1000 mL) = 4.23 US cups, often rounded to 4 1/4 cups. For metric cups: 1 liter = 4 metric cups exactly.

Why do recipes use cups instead of mL?

US recipes traditionally use cups because the imperial system is standard in America. Cups are convenient for home cooking since most US kitchens have measuring cups. However, professional bakers and international recipes prefer weight (grams) or volume (mL) measurements for accuracy.

Can I use a regular drinking glass as a measuring cup?

No! Regular glasses vary widely in size. A standard US cup is exactly 236.588 mL (8 fluid ounces). Always use proper measuring cups or a kitchen scale for accurate results, especially in baking.

Should I convert cups to mL or grams for baking?

For best results, convert to grams using a kitchen scale. Different ingredients have different densities (1 cup flour ≠ 1 cup sugar in grams), but they occupy the same volume in mL. Weight is more accurate than volume for baking. See our cups to grams converter for ingredient-specific conversions.
