The volt (symbol: V) is the unit of electric potential, electric potential difference , and electromotive force in the International System of Units (SI). [1]
The SI unit of work per unit charge is the joule per coulomb, where 1 volt = 1 joule (of work) per 1 coulomb of charge. [citation needed] The old SI definition for volt used power and current; starting in 1990, the quantum Hall and Josephson effect were used, [10] and in 2019 physical constants were given defined values for the definition of all SI units.

In short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1) or volt (V). The electric potential at infinity is assumed to be zero.
In general, the masses of all hadrons are of the order of 1 GeV/c 2, which makes the GeV/c 2 a convenient unit of mass for particle physics: [4] 1 GeV/ c 2 = 1.782 661 92 × 10 −27 kg . The atomic mass constant ( m u ), one twelfth of the mass a carbon-12 atom, is close to the mass of a proton.

Cruis'n USA runs on a Midway V-Unit, which is very different from what would become the Silicon Graphics based Nintendo 64. The Midway V-unit consists of a 50 MHz TMS32031 CPU, a 10 MHz ADSP-2115 DSP for sound, and a custom 3D chip that can render perspective-correct but unfiltered quads at a high resolution (512 × 400 pixels).
