Recipe Conversion Guide

Recipe conversion involves scaling ingredients proportionally and understanding how different measurements relate to each other. This tool helps maintain the correct ratios for successful cooking and baking.

Common Volume Conversions
  • 1 cup = 16 tablespoons = 48 teaspoons = 240ml = 8 fl oz
  • 1 tablespoon = 3 teaspoons = 15ml = 0.5 fl oz
  • 1 teaspoon = 5ml = 0.17 fl oz
  • 1 pint = 2 cups = 480ml = 16 fl oz
  • 1 quart = 4 cups = 960ml = 32 fl oz
  • 1 gallon = 16 cups = 3.8 liters = 128 fl oz
Common Weight Conversions
  • 1 pound = 16 ounces = 454 grams
  • 1 ounce = 28.35 grams
  • 1 kilogram = 2.2 pounds = 1000 grams
Cooking Tips
  • Scaling Rules: Most ingredients scale linearly, but seasonings may need adjustment
  • Baking Precision: Baking recipes require more precise measurements than cooking
  • Leavening Agents: Baking powder/soda may not scale perfectly - test in small batches
  • Cooking Times: May need adjustment when scaling recipes significantly
  • Pan Sizes: Consider if your cookware can accommodate the scaled recipe

Disclaimer: This calculator provides estimates for recipe conversion. Actual results may vary based on ingredient density, cooking methods, and personal preferences. For baking, precise measurements are particularly important. Always taste and adjust seasonings as needed.

Scaling Formula:
Scaled Amount = Original Amount × (Desired Servings ÷ Original Servings)

Questions About Scaling Recipes

Can I use this tool for baking recipes?

Yes. It’s ideal for baking, where precision matters. Use the metric equivalents or fractional conversions for better accuracy.

What if the scaled ingredient is too small to measure?

Start with the closest practical measurement. The tool offers rounding to help make measurements more usable.

Can I substitute oil for butter using this?

While this tool does not convert butter to oil directly, you can apply the common oil to butter ratio manually (usually 1:0.75). It complements a butter substitution guide for healthier baking.

Does it work for weight and volume?

Yes. You can enter ingredients by weight (grams, ounces) or volume (cups, millilitres), and the tool helps convert and scale accordingly.
