Paste your grocery list (one item per line, quantity first) and choose a multiplier to scale every line at once.
This calculator reads the leading number on each line of your list (whole numbers, decimals, or simple fractions like 1/2 or 1 1/2), multiplies it by your chosen scale factor, and rebuilds the line with the new quantity — leaving the rest of each line (the unit and ingredient name) unchanged. It's useful for doubling a week's grocery list for a dinner party, or scaling a shopping list down for a smaller household.
Source: This tool applies straightforward multiplication to each line's leading quantity; the underlying principle is the same proportional recipe-scaling method used by this site's Recipe Scaler & Multiplier calculator, applied across a whole shopping list instead of a single recipe.
Yes — it recognizes whole numbers, decimals, simple fractions like 1/2, and mixed numbers like 1 1/2, and scales the leading quantity on each line while leaving the unit and ingredient name unchanged.
No — the Recipe Scaler is built for scaling one recipe's ingredient list to a new yield. This tool is meant for a whole grocery list across multiple recipes or a week's shopping, such as doubling everything for a dinner party.
Lines without a recognizable leading quantity (like a note or header) are left unchanged in the output rather than being skipped or causing an error.
