Frequently asked questions
- What ingredient formats are supported?
- Anything that starts with a number — whole numbers, decimals, fractions like 1/2, mixed fractions like 1 1/2, and unicode fractions like ½, ¾, ⅓.
- Will it convert cups to grams?
- No — it only scales the quantity, keeping your original units. A cups → grams converter is a separate tool.
- Why does the result use ½ instead of 0.5?
- If your input used a fraction, we keep the result as a fraction. If you wrote 0.5, you'll get 1.0 when doubled.
- What about lines without numbers — methods, headings?
- They pass through unchanged. Only lines starting with a quantity are scaled.
- Is my recipe stored anywhere?
- No. Recipes stay in your browser tab.
