Table 1 – Système International (SI) Units

Entity Abbreviation Name
Fundamental units Length \text{m} meter
Mass \text{kg} kilogram
Time \text{s} second
Current \text{A} ampere
Supplementary unit Angle \text{rad} radian
Derived units Force \text{N} = \text{kg} \cdot \text{m} / \text{s}^2 newton
Energy \text{J} = \text{kg} \cdot \text{m}^2 / \text{s}^2 joule
Power \text{W} = \text{J} / \text{s} watt
Pressure \text{Pa} = \text{N} / \text{m}^2 pascal
Frequency \text{Hz} = 1/ \text{s} hertz
Electronic potential \text{V} = \text{J} / \text{C} volt
Capacitance \text{F} = \text{C} / \text{V} farad
Charge \text{C} = \text{s} \cdot \text{A} coulomb
Resistance \Omega = \text{V} / \text{A} ohm
Magnetic field \text{T} = \text{N} / (\text{A} \cdot \text{m}) tesla
Nuclear decay rate \text{Bq} = 1 / \text{s} becquerel
