Common Cooking Conversions

Volume:

1 cup = 16 tbsp
1 tbsp = 3 tsp
1 cup = 8 fl oz
1 pint = 2 cups

Weight:

1 lb = 16 oz
1 kg = 2.2 lbs
1 oz = 28.35 g
1 cup flour ≈ 120g

Temperature:

°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
350°F = 175°C
400°F = 200°C

Frequently Asked Questions About Recipe Scaling

How do you scale down a recipe?

Divide each ingredient amount by the scaling factor. For example, to halve a recipe, divide all amounts by 2. This calculator does the math automatically when you enter your desired servings.

Can I scale baking recipes the same way?

Most ingredients scale linearly, but leavening agents (baking powder, yeast), spices, and salt may need adjustment. Baking is chemistry, so extreme scaling can affect texture and rise.

What happens to cooking time when scaling?

Cooking time does not scale proportionally. Larger batches may need slightly longer cooking, while smaller batches cook faster. Check for doneness using visual cues and thermometers.

How do you convert fractions when scaling?

Multiply the fraction by your scale factor. For example, ½ cup × 1.5 = ¾ cup. This calculator displays common fractions automatically for easy measuring.

Is there a limit to how much I can scale a recipe?

Scaling beyond 4x or below ¼x often produces unreliable results. Equipment limitations, heat distribution, and ingredient behavior change at extreme scales. For large batches, consider making multiple smaller batches.
