WHAT THIS TOOL DOES

This recipe scaler changes ingredient quantities when you want more or fewer servings than the original recipe.

It is useful for doubling recipes, halving recipes, meal prep, batch cooking and adjusting recipes for guests.

Use the same unit style as your recipe: grams, millilitres, teaspoons, cups or items.

HOW TO USE IT

Page 1 sets the original servings, new servings, rounding and unit.

Page 2 enters ingredient names and current amounts.

Press SOLVE to see the scaled recipe on Page 3.

RECIPE SCALING FORMULA

Scale factor = new servings ÷ original servings.

New ingredient amount = old ingredient amount × scale factor.

Every ingredient is multiplied by the same scale factor.

Original servings must be more than zero.

WORKED EXAMPLE

Original recipe serves 4. New recipe should serve 6.

Scale factor = 6 ÷ 4 = 1.5.

200g flour becomes 200 × 1.5 = 300g.

300ml milk becomes 300 × 1.5 = 450ml.

WHO USES IT

Home cooks use it when a recipe serves the wrong number of people.

Bakers use it to resize quantities while keeping recipe proportions the same.

It is useful for batch cooking, meal prep, party food planning and reducing leftovers.
