Frequently asked questions
Is pound-force the same as pound-mass?
No. This converter is for mass units, not force.
Does mass change on another planet?
Mass stays the same, while gravitational weight changes. This converter handles mass units rather than gravitational force.
Limits and interpretation
- The page converts common mass units; everyday use often says weight, but force in newtons is a different quantity.
- Troy ounces and avoirdupois ounces are not the same and must not be mixed for precious metals or trade.
