Scale a recipe 1.5×

Halving or one-and-a-half-ing a recipe is mostly arithmetic. LocalCupGrams includes a simple paste scaler: paste lines that start with a number (including fractions like 1/2 or 1 1/2), set the factor to 1.5, and scale.

What it does

Multiplies the leading quantity on each line.
Leaves ingredient names and units as you typed them.
Keeps everything in this tab — no account, no upload.

What it does not do

It does not convert cups to grams for you (use the ingredient converter for that).
It does not rewrite “2 eggs” into chemistry-perfect ratios for yeast or leavening — cook’s judgment still applies.
It does not claim food-safety timing for scaled batches.

Tip: convert tricky volume ingredients to grams first, then scale the gram lines — weight scales more cleanly than packed cups.
