Recipe Batch Scaler

Adjust a recipe to a different number of servings. Scale ingredient quantities, keep fractions exact, and copy or print the complete list.

Use 1.5, 3/4, 1 1/2 or ½. Keep units in their own field.

Fractions are exact. Decimal previews round to three places; ≈ marks rounding. Units, cooking time, and temperature are unchanged.

How the multiplier works

Divide the servings you want by the servings the original recipe makes. Multiply every ingredient quantity by that same factor. Going from four servings to six gives 6 ÷ 4 = 1.5. Halving a recipe uses 0.5; doubling it uses 2. Enter your actual serving counts instead of rounding the multiplier before calculation.

Try the four-to-six example

The sample list has 1 1/2 cups of rice, 2 cans of chickpeas, and 1/2 teaspoon of cumin for four servings. For six, the list becomes 2 1/4 cups, 3 cans, and 3/4 teaspoon. Compare both columns, then replace the sample with your own ingredients. This is an arithmetic example, not a complete cooking recipe.

Enter quantities without changing their meaning

Use a dot for decimals and a slash for fractions. Mixed numbers need a space, such as 2 1/3; common fraction symbols such as ½ also work. Enter only the number in Quantity. Put cups, grams, tablespoons, or another label in Unit. Leave Unit blank for counted ingredients. Ranges and “to taste” are not numeric quantities; keep those instructions in your original recipe.

Measure and cook with judgment

The tool changes amounts, not ingredient density or cooking instructions. A cup of flour does not become grams here, and unit labels are preserved exactly. Fractional eggs or package counts need a practical measuring decision; they are not rounded to whole items automatically. Keep oven temperature and cooking time separate. A larger batch may need a different pan or several batches; check the original recipe rather than multiplying its cooking time.

Frequently Asked Questions

Does it change cups into grams?

No. Units remain exactly as entered. Converting volume to weight needs ingredient-specific information that this tool does not assume.

Why is the decimal marked with ≈?

The exact fraction is shown first. Decimal previews round half up to three places, so 2/3 displays as ≈ 0.667. Very small positive values display as <0.001 rather than zero.
