masseenheter

Massenheter, also known as mass units, are standardized units used to measure the mass of an object. The most commonly used mass unit in the International System of Units (SI) is the kilogram (kg). The kilogram is defined as the mass of the International Prototype of the Kilogram, a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in France.

Other mass units include the gram (g), which is equal to one-thousandth of a kilogram, and the tonne (t), which is equal to one thousand kilograms. In the United States, the pound (lb) and the ounce (oz) are commonly used, with one pound being equal to 16 ounces and one pound being approximately 0.45359237 kilograms.

Mass is a fundamental property of matter and is distinct from weight, which is the force exerted on an object due to gravity. Mass is measured using a balance or a scale, while weight is measured using a spring scale or other force-measuring device. The concept of mass is crucial in physics and engineering, as it is used to calculate various physical quantities such as density, momentum, and energy.
