Cooking Measurements Guide

June 20, 2026 • 6 min read

Cooking should be enjoyable, not frustrating. Understanding measurements and conversions makes following recipes much easier — especially when switching between US and metric systems.

Basic US to Metric Conversions

• 1 teaspoon = 5 milliliters
• 1 tablespoon = 15 milliliters (3 teaspoons)
• 1 fluid ounce = 30 milliliters
• 1 cup = 240 milliliters (16 tablespoons)
• 1 pint = 473 milliliters
• 1 quart = 946 milliliters
• 1 gallon = 3.785 liters

Common Mistakes to Avoid

• Don't confuse fluid ounces with weight ounces
• US and Imperial (UK) measurements are different
• 1 US cup = 240ml, but many countries use 250ml cups
