Metre squared per second

Metre squared per second or square meter per second is the SI derived unit of kinematic viscosity, specific relative angular momentum and thermal diffusivity. The unit is written in symbols as m²/s or m²·s⁻¹ or m²s⁻¹.

Specific relative angular momentum

Specific relative angular momentum is defined as the cross product of the relative position and relative velocity. The unit may be better understood when phrased as "metre per second times metre", i.e. the velocity of an object with respect to a position.
