How does the recipe scaler calculate quantities?

It divides the target servings by the original servings to get a multiplier, then multiplies each ingredient quantity by that factor. For example, scaling from 4 to 6 servings gives a 1.5x multiplier.

Why does it show fractions instead of decimals?

Fractions like 1/2 or 2/3 are much easier to measure in the kitchen than decimals like 0.5 or 0.667. The tool automatically converts decimal results to the nearest common cooking fraction.

What units can I convert between?

The built-in conversion table covers cups, tablespoons (tbsp), teaspoons (tsp), fluid ounces (fl oz), and milliliters (mL). Dry weight units like grams and ounces are also listed for reference.

Does the tool work for baking recipes?

Yes. You can scale baking recipes by servings. Keep in mind that for large scaling factors, baking times and pan sizes may need adjustment — the tool handles the math, but you may need to adapt technique.
