Weight Converters
Pick a family to convert between defined metric and imperial weight units using stable international definitions.
Explanation

How to use this hub
- Choose a converter family.
- If converting to/from grams from a volume unit, select an ingredient.
- For pure unit changes (volume↔volume or weight↔weight), use universal conversions.
If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.
