Weight and volume are different
A fluid ounce measures volume; an ounce measures weight. They only match in special cases, so choose the unit type written in the recipe.

How it works
How to convert cups, grams, ounces, and oven temperatures
Start by identifying whether the recipe measurement is volume, weight, or temperature. Units convert reliably within the same group; moving from cups to grams also requires the ingredient's density.
- 01
Choose the amount and unit
Enter the quantity from the recipe, then select its current unit. The destination list stays within the matching volume, weight, or temperature group. - 02
Select the unit you need
Convert between US kitchen volume measures, metric volume, common cooking weights, or Fahrenheit and Celsius. Swap the direction with one click. - 03
Use ingredient estimates carefully
For cups to grams, choose the specific ingredient. Flour, sugar, butter, honey, and other foods have different weights for the same cup volume.
Quick reference
Common kitchen measurement conversions
Pinch uses US customary volume measures and standard metric equivalents. Temperature results can be rounded to the nearest practical oven setting.
| Measure | Equivalent | Type |
|---|---|---|
| 1 tablespoon | 3 teaspoons | Volume |
| 1 US cup | 16 tablespoons / 236.588 mL | Volume |
| 1 fluid ounce | 29.5735 mL | Volume |
| 1 pound | 16 ounces / 453.592 g | Weight |
| 350 F | 176.7 C (about 177 C) | Oven temperature |
Practical notes
Know what the number represents
A cup depends on the ingredient
One cup of flour weighs much less than one cup of honey. Use the ingredient selector for cup-to-gram estimates instead of converting volume directly to weight.
Baking rewards precision
Scooping technique and ingredient packing change cup weights. When the recipe supplies grams, a kitchen scale is more reliable than a volume conversion.
Common questions
What cooks usually ask
Converting a full ingredient list? Scale the quantities first with the recipe scaler, then convert only the unfamiliar units.
How many grams are in one cup of flour?
Pinch estimates 1 US cup of all-purpose flour at 120 grams. Published references vary because flour can be spooned, sifted, or packed differently, so use the original recipe's stated weight when available.
Are ounces and fluid ounces interchangeable?
No. Ounces are a unit of weight and fluid ounces are a unit of volume. Convert fluid ounces with cups or milliliters; convert weight ounces with grams or pounds.
How do I convert Fahrenheit to Celsius for an oven?
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9. For example, 350 F is about 176.7 C, commonly rounded to 175 C or 180 C depending on the oven's available settings.
