About these units
Ounce (oz)
The ounce is used for weight in the US customary and imperial systems. It is common in US recipes, food packaging, and portion sizes. Note that fluid ounces (fl oz) measure volume, not weight.
- 1 oz = 28.3495 grams.
- 16 oz = 1 pound.
- Ounces and fluid ounces are different units — oz is weight, fl oz is volume.
Kilogram (kg)
The kilogram is the base unit of mass in the metric system and is used on food labels and in professional kitchens internationally.
- 1 kg = 1000 grams.
- 1 kg = 35.274 oz.
- Many kitchen scales support both oz and kg modes.
Tips
When scaling recipes, convert to metric first (mL/g), scale, then convert back if needed.
Cups to grams depends on the ingredient (flour vs sugar vs butter).
