Recipe scaler FAQ

How does the scaler know which numbers to change?

It looks at the start of each line for a quantity — whole number, decimal, fraction, mixed number, or unicode fraction — and scales it. The rest of the line stays untouched.

Can I scale by servings instead of a multiplier?

Yes — enter the recipe's original servings and your target, and the multiplier is calculated automatically.

Why do some fractions look approximate?

Results round to the nearest common kitchen fraction (eighths, thirds, halves), since that's what measuring cups and spoons actually support.
