The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.

The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
the Planck mass (about 2.18 × 10 −8 kg), a quantity derived from fundamental constants; the solar mass (M ☉), defined as the mass of the Sun, primarily used in astronomy to compare large masses such as stars or galaxies (≈ 1.99 × 10 30 kg) the mass of a particle, as identified with its inverse Compton wavelength (1 cm −1 ≘ 3.52 × ...

Mass and weight of a given object on Earth and Mars.Weight varies due to different amount of gravitational acceleration whereas mass stays the same.. In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities.
