Most common cooking weight conversions
Grams to ounces
Divide grams by 28.35. So 100 g is about 3.5 oz and 250 g is about 8.8 oz.
Ounces to grams
Multiply ounces by 28.35. So 4 oz is 113 g and 8 oz is 227 g.
Pounds to kilograms
Multiply pounds by 0.454. So 1 lb is 0.45 kg and 5 lb is 2.27 kg.
8 oz in grams & 1 lb in kg
8 ounces is 227 g (half a pound), and 1 pound is 0.454 kg or 454 g.
Metric vs imperial weight
The metric system uses grams and kilograms; the imperial and US customary systems use ounces and pounds. The conversions are exact constants – 1 ounce = 28.3495 g and 1 pound = 453.592 g – so any differences you see come only from rounding. These are weight (avoirdupois) ounces, not fluid ounces, which measure volume.
Weight vs volume
This converter handles weight only – mass to mass. Converting a volume such as cups or millilitres into a weight is a different job, because the answer depends on what you are measuring: a cup of flour and a cup of honey weigh very different amounts. For those, use the Ingredient Weight Converter, which factors in each ingredient’s density.
Why recipes increasingly use grams
More recipes are written in grams because weight is exact and repeatable. A gram is a gram regardless of how it is scooped or packed, so a weighed recipe turns out the same every time, scales cleanly to any batch size, and is easy to follow with a single bowl on a tared scale.
Common food weight examples
| Item | Approx. weight |
|---|---|
| Large egg | about 50 g |
| Stick of butter | 113 g (4 oz) |
| Cup of all-purpose flour | about 125 g |
| Standard can of beans | about 400 g |
| US cup of water | about 237 g |
For volume-to-weight on specific ingredients, the Ingredient Weight Converter gives exact per-ingredient figures.
Using a kitchen scale
- Place the bowl on the scale and press tare (zero) before adding each ingredient.
- Switch to grams for small amounts – they are far more precise than fractions of an ounce.
- Weigh sticky ingredients straight into the bowl to avoid loss.
- Check the scale against a known weight occasionally to confirm accuracy.
