Recipe Scaler & Converter
Paste a whole ingredient list, then halve it, double it or switch it to grams
Paste a whole ingredient list and scale it up or down, or convert the entire recipe to grams. It reads mixed numbers, unicode fractions and ranges.
What scales linearly and what does not
- Flour, sugar, butter, milk, eggs, chocolate and fruit all scale in a straight line.
- Salt and spices scale arithmetically but not perceptually — scale to about 1.75× when doubling, then taste.
- Leavening over-inflates above about 3× a batch; reduce it by roughly 10%.
- Pan size and baking time do not scale at all.
Frequently asked questions
How do I double a recipe?
Paste the ingredient list and tap 2×. Baking times do not double — a deeper batter needs longer at a lower temperature.
Is anything uploaded?
No. Parsing and scaling happen entirely in your browser.
