The table below is based on the [[kilogram]] (kg), the base unit of mass in the [[International System of Units]] ([[SI]]). The kilogram is the only standard unit to include an [[SI prefix]] (''kilo-'') as part of its name. The ''[[gram]]'' (10<sup>−3</sup> kg) is an SI derived unit of mass. However, the ''names'' of all SI mass units are based on ''gram'', rather than on ''kilogram''; thus 10<sup>3</sup> kg is a ''megagram'' (10<sup>6</sup> g), not a "kilokilogram".
 
The ''[[tonne]]'' (t) is a SI-compatible unit of mass equal to a megagram, or 10<sup>3</sup> kg. The unit is in common use for masses above about 10<sup>3</sup> kg and is often used with SI prefixes.
 
===Other units===
Other units of mass are in use. Historical units include the [[Stone (imperial mass)|stone]], the  [[Pound (mass)|pound]], the [[Carat (mass)|carat]] and the [[Grain (unit)|grain]].
 
For subatomic particles, physicists use the mass equivalent to the energy represented by an electron volt ([[Electronvolt|eV]]). At the atomic level, chemists use the mass of one-twelfth of a carbon-12 atom (the [[Atomic mass unit|dalton]]). Astronomers use the [[Solar mass|mass of the sun]] <math>(\begin{smallmatrix}M_\odot\end{smallmatrix})</math>.

=== Below 10<sup>&minus;24</sup> kg ===
 
Unlike other physical quantities, mass-energy does not have an ''a priori'' expected minimal quantity, as is the case with [[Planck time|time]] or [[Planck length|length]], or an observed basic quantum as in the case of [[Elementary charge|electric charge]]. [[Planck's law]] allows for the existence of photons with arbitrarily low energies. Consequently, there can only ever be an experimental lower bound on the mass of a supposedly massless particle; in the case of the photon, this confirmed lower bound is of the order of 3×10<sup>−27</sup> eV = 10<sup>−62</sup> kg.
