What is the difference between kilogram and ounce?

Kilogram is the SI base unit of mass defined by fundamental constants, while ounces are customary units with the common avoirdupois ounce equal to exactly 28.349523125 grams.

Can I use this converter for precious metals?

This converter uses the avoirdupois ounce, which differs from the troy ounce used for precious metals, so results may not be suitable for precious metals trading.

Why should I be careful about mixing units?

Mixing SI units like kilogram with customary units like ounce without consistent conversion can lead to measurement errors and confusion.
