Cooking and Baking
Precision matters in baking. Converting recipe measurements:
| Recipe calls for | Grams |
|---|---|
| 1 oz butter | 28.3 g |
| 4 oz flour | 113.4 g |
| 6 oz sugar | 170.1 g |
| 8 oz cream cheese | 226.8 g |
| 12 oz chocolate | 340.2 g |
Professional bakers prefer grams for accuracy because cup measurements can vary significantly depending on how ingredients are scooped.
Troy Ounces vs. Avoirdupois Ounces
For precious metals (gold, silver, platinum), a different ounce is used:
- Troy ounce = 31.1035 grams
- Avoirdupois ounce = 28.3495 grams
When gold prices are quoted "per ounce," they mean troy ounces. This tool uses avoirdupois ounces (the common household ounce).
Postal and Shipping
Many postal services use ounces for letter weight:
- Standard letter: up to 1 oz (28.3 g)
- Each additional ounce adds extra postage
- International mail often requires gram measurements
