Question

what is the unit of m2 in physics​

Answer 1

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.

Answer 2

One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg−1, or N/kg. Thus, the Earth's gravitational field (near ground level) can be quoted as 9.8 metres per second squared, or the equivalent 9.8 N/kg.
