About these units
Mass is the amount of matter in an object; in everyday speech it is called weight. The SI base unit is the kilogram, defined since 2019 through the Planck constant.
The pound and ounce are used in the United States and alongside metric units in the United Kingdom, where body weight is often given in stone. Since 1959 the pound is exactly 0.45359237 kg, so every conversion here is exact.
Precious metals are weighed in troy ounces and gemstones in metric carats.
