The method, explained

Converted value = input × kilograms per source unit ÷ kilograms per target unit. One international avoirdupois pound is exactly 0.45359237 kilograms.

A WORKED EXAMPLE

1 kilogram is approximately 2.20462 pounds. A 16-ounce avoirdupois quantity is exactly 1 pound.

What to keep in mind

This everyday weight converter converts mass, not force. Ounces are avoirdupois ounces, not fluid or troy ounces.

Common questions

Can this convert fluid ounces?

No. Fluid ounces measure volume, which requires a volume converter or a material density.

Is this suitable for precious metals?

Precious metals often use troy ounces. This tool uses ordinary avoirdupois ounces, so select a dedicated troy conversion instead.
