Weight and Mass Units

Mass is both a property of a physique and a quantity of its resistance to acceleration (a change in its state of movement) when a net force is used. A things's mass also determines the strength of its gravitational pull-force to other bodies.

The standard SI unit of mass is the kg (kg). In physics, mass is not the exact same as weight, even though mass is frequently figured out by measuring the object's weight utilizing a spring scale, rather than balance scale comparing it straight with recognized masses. An item on the Moon would weigh less than it does on Earth since of the lower gravity, however it would still have the exact same mass. This is since weight is a force, while mass is the property that (together with gravity) figures out the strength of this force.


The standard International System of Units (SI) unit of mass is the kg (kg). The kg is 1000 grams (g), first specified in 1795 as one cubic decimeter of water at the melting point of ice. Due to the fact that accurate measurement of a cubic decimeter of water at the correct temperature level and pressure was hard, in 1889 the kilogram was redefined as the mass of the worldwide prototype of the kilogram of cast iron, and hence became independent of the meter and the properties of water.

The mass of the global model and its supposedly similar nationwide copies have actually been found to be drifting over time. The re-definition of the kilogram and a number of other units occurred on 20 May 2019, following a last vote by the CGPM in November 2018. [3] The brand-new definition utilizes only invariant quantities of nature: the speed of light, the caesium hyperfine frequency, and the Planck constant. [4]

Other units are accepted for use in SI:

  • the tonne (t) (or "metric ton") is equivalent to 1000 kg.
  • the electronvolt (eV) is a unit of energy, but due to the fact that of the mass-- energy equivalence it can quickly be transformed to a unit of mass, and is often used like one. In this context, the mass has units of eV/c2 (where c is the speed of light). The electronvolt and its multiples, such as the MeV (megaelectronvolt), are typically utilized in particle physics.
  • the atomic mass unit (u) is 1/12 of the mass of a carbon-12 atom, around 1.66 × 10 − 27 kg. [note 2] The atomic mass unit is hassle-free for expressing the masses of particles and atoms.

Outside the SI system, other units of mass include:

  • the slug (sl) is an Imperial unit of mass (about 14.6 kg).
  • the pound (pound) is a unit of both mass and force, utilized mainly in the United States (about 0.45 kg or 4.5 N). In scientific contexts where pound (force) and pound (mass) require to be differentiated, SI units are generally utilized instead.
  • the Planck mass (mP) is the optimum mass of point particles (about 2.18 × 10 − 8 kg). It is used in particle physics.
  • the solar mass (M ☉) is specified as the mass of the Sun. It is primarily utilized in astronomy to compare big masses such as stars or galaxies (≈ 1.99 × 1030 kg).
  • the mass of a really small particle might be determined by its inverse Compton wavelength (1 cm − 1 ≈ 3.52 × 10 − 41 kg).
  • the mass of a large star or black hole might be determined with its Schwarzschild radius (1 cm ≈ 6.73 × 1024 kg).
