One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points

1 V = W/A

Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units (m, kg, s, and A) as

V=J/C

Nominal voltages of familiar sources:
Nerve cell resting potential: ~75 mV
Single-cell, rechargeable NiMH or NiCd battery: 1.2 V
