Cooking Measurement Converter — Cups, Tbsp, Tsp, mL, Grams & More

The Formula

Cooking measurement conversion uses linear scaling factors relative to milliliters (mL). Volume-to-volume conversions are exact. Volume-to-weight conversions assume the ingredient has the same density as water (1 g/mL), which is NOT accurate for most ingredients — see the notes below.

How to Use This Calculator

1. 1

   Enter the measurement value you want to convert.

2. 2

   Select the current measurement unit from the "From" dropdown.

3. 3

   Select the desired measurement unit from the "To" dropdown.

4. 4

   The converted value is displayed instantly. Volume-to-weight conversions assume the ingredient is water (1 g = 1 mL). For accurate weight conversions of other ingredients, use a kitchen scale or ingredient-specific conversion chart.

Quick Reference

Common Applications

• Baking: accurately measuring flour, sugar, butter, and liquids in cups, grams, or milliliters for consistent results
• Recipe scaling: adjusting recipes from 4 servings to 8 servings while maintaining correct proportions
• International cooking: converting between US customary (cups, tsp, tbsp) and metric (mL, grams) measurements
• Meal prep: scaling ingredient quantities for weekly meal preparation and portion control
• Nutrition tracking: converting recipe yields to calculate per-serving nutritional information
• Canning and preserving: calculating precise liquid measurements for safe water bath and pressure canning

Understanding the Concept

Cooking measurements are a specialized subset of volume measurement with their own unique units: teaspoons, tablespoons, cups, and fluid ounces. The US customary system dominates American recipes and cookbooks, while the rest of the world uses milliliters and grams. This converter handles both, plus weight equivalents for water. Important caveat: volume-to-weight conversions (cups to grams, tablespoons to ounces) differ dramatically by ingredient. One cup of flour weighs about 120 g, one cup of sugar weighs 200 g, and one cup of water weighs 236.6 g. This converter provides water-equivalent weights only. For accurate baking, use a kitchen scale and ingredient-specific conversion charts. Professional bakers overwhelmingly prefer weight measurements (grams) over volume (cups) because weight is consistent — a cup of flour can vary from 110 g to 160 g depending on how it is scooped. The "spoon and level" method (spooning flour into a cup then leveling) gives about 120 g, while dipping the cup into the flour gives closer to 150 g. For everyday cooking, volume measurements are fine, but for baking — where chemical ratios matter — weighing ingredients is far more reliable.
