How to use Weight / Mass Converter
Everyday “weight” conversions usually mean mass. This tool converts mass units through kilograms. Pounds and ounces use the ordinary avoirdupois system, and a tonne means a metric tonne of 1000 kilograms.
Precious metals may be quoted in troy ounces, which are different from the ordinary ounce provided here. Newtons measure force, so they are not included in this mass converter.

Questions about this calculation
Can I use the ounce conversion for gold?
Check the unit. Gold is often quoted in troy ounces, which this tool does not support.
Is a tonne the same as a US ton?
No. This tool’s metric tonne is 1000 kilograms; US short tons are not included.
