[[File:Lorentz factor 2.png|thumb|Lorentz factor {{mvar|γ}} as a function of fraction of given velocity and speed of light. Its initial value is 1 (when {{math|''v'' {{=}} 0}}); and as velocity approaches the speed of light {{nobr|(''v'' → ''c'')}} {{mvar|γ}} increases without bound {{nobr|({{mvar|γ}} → ∞).}}]]

In the table below, the left-hand column shows speeds as different fractions of the speed of light (i.e. in units of {{mvar|c}}). The middle column shows the corresponding Lorentz factor, the final is the reciprocal. Values in bold are exact.
