Recipe Converter – Scale Recipe Servings and Convert Measurement Units
Recipe converter scales ingredient amounts for desired serving size and converts measurement units (cups, oz, tbsp) to metric measurements (ml, g, tbsp). Works for both scaling up and down.
Enter original serving size and desired serving size, and the calculator shows new ingredient amounts. You can also automatically convert units and get ingredients in metric measurements.
How to Double a Recipe?
Most ingredient amounts scale directly by multiplying or dividing, but note: baking is more precise — leavening agents (baking powder, baking soda) don't always scale linearly in large batches. Start with 75% of scaled spice amounts and taste-test. Baking time doesn't double when batch size doubles — monitor internal temperature instead.

Enter the original serving size and desired serving size, and the converter calculates new ingredient amounts.
- Scale all ingredients from the original serving size to your desired size.
- Enter serving size as number of people or as a multiplier.
- Results are shown in clearly measurable units.
Mathematical scaling is straightforward, but not all ingredients scale linearly.
- Spices and salt usually don't scale directly – start with less and taste.
- Baking leavening agents often need more precise ratio adjustments in large batches.
- Cooking time and temperature may change as serving size increases.
Recipe scaling is a starting point – final fine-tuning is done by tasting.
- When using oven, larger batches may require longer cooking time.
- Very large or small servings may require technique changes.
- Tool doesn't save your recipes – copy results if needed.
