Weight & Mass Conversion

Understanding Weight and Mass Units

Mass is a measure of the amount of matter in an object. It remains constant regardless of location. The SI base unit of mass is the kilogram (kg).

Weight is the force exerted on an object due to gravity. It can vary depending on location. Though scientifically different from mass, in everyday context, weight and mass units are often used interchangeably.

Kilogram (kg), gram (g), milligram (mg), metric ton, etc. - based on the decimal system and used worldwide in science and commerce.

Pound (lb), ounce (oz), stone (st), ton (short & long), etc. - historically used in English-speaking countries, still common in the US and UK.

Atomic mass unit (u), electron mass, etc. - used in scientific contexts like particle physics and chemistry.

Grain, carat, drachma, etc. - traditional units, some still used in specific industries like jewelry.

Talent, mina, shekel, etc. - ancient units mentioned in historical and religious texts.
