Units of Mass – An Overview of the Most Common Measures
Mass is one of the fundamental physical quantities we encounter almost daily – while shopping, cooking, or weighing objects. Depending on the country, field of science, or application, different units of mass are used. Below is an overview of the most commonly used units, including those from the SI system and others.
SI Units of Mass
The SI (International System of Units) is the globally accepted system for measurements. For mass, the base unit is:
- Kilogram (kg) – the base unit of mass in the SI system. 1 kg = 1000 g.
- Gram (g) – 1 g = 0.001 kg. Commonly used in everyday life, e.g., cooking or shopping.
- Milligram (mg) – 1 mg = 0.001 g. Used for very small masses, such as in pharmaceuticals.
- Tonne (t) – 1 t = 1000 kg. Used in industries and for large-scale transportation.
Quintal – A Non-SI Unit
Quintal (q) – although commonly used in practice, it is not part of the SI system. 1 quintal = 100 kilograms. It is most often used in agriculture to express the weight of crops like grains or potatoes.
Imperial Units of Mass
- Ounce (oz) – 1 oz ≈ 28.35 g. Often used for weighing spices, jewelry, or small items.
- Pound (lb) – 1 lb = 16 oz ≈ 0.4536 kg. Common in the US and UK.
- Stone (st) – 1 st = 14 lb ≈ 6.35 kg. Mainly used in the UK for measuring body weight.
Specialized and Historical Units of Mass
- Carat (ct) – used in jewelry. 1 ct = 0.2 g.
- Grain – a historical unit of mass. 1 grain ≈ 64.8 mg. Formerly used in pharmacy and for measuring gunpowder.
