- Divide grams by 28 for a quick ounce estimate. 100g is about 3.5 oz, 200g is about 7 oz. For baking, where precision matters, use the exact factor: grams / 28.3495.
- Postal rates often have weight thresholds in ounces (US) or grams (international). A standard US letter must be under 1 oz (28.3g) for the base stamp price. Going over even by 1 gram requires additional postage.
- Precious metals are measured in troy ounces (31.1g), not standard ounces (28.3g). One troy ounce of gold weighs 10% more than a standard ounce. Always verify which ounce type is referenced in metal pricing.
