Scaling factor

×1.50

Every quantity below is multiplied by 1.50.

Ingredients

→ 3 cups

→ ¾ cups

→ 4 ½

Quantities are rounded to fractions you can actually measure. Scaling works cleanly for most things, but baking times, tin sizes and raising agents do not scale linearly — a doubled cake needs a bigger tin and longer in the oven, not twice the baking powder.
