About Mass Units

Mass is a fundamental property of matter that measures the amount of matter in an object. It is commonly measured in various units depending on the region and application.

Common Mass Units
  • Metric System: Kilograms (kg), Grams (g), Milligrams (mg), Metric Tons (t)
  • Imperial/US System: Pounds (lb), Ounces (oz), Stone (st), US Tons (ton), Long Tons
  • Other Units: Carats (ct) for gemstones, Grains for pharmaceuticals and bullets, Atomic Mass Units (u) for atomic particles
Interesting Facts

Here are some interesting facts about mass measurements:

  • The kilogram was the last SI unit to be defined by a physical object (the International Prototype Kilogram) until 2019
  • Now the kilogram is defined in terms of the Planck constant
  • The carat (200 mg) used for gemstones originated from the carob seed, which was used as a reference weight
  • While mass and weight are often used interchangeably in everyday language, they are different physical quantities
