Symbol
- $\mathrm {m \, s^{-2} }$ or $\mathrm {m / s^2}$
The symbol for the metre per second squared is $\mathrm {m \, s^{-2} }$ or, less formally, $\mathrm {m / s^2}$.
The $\LaTeX$ code for \(\mathrm {m \, s^{-2} }\) is \mathrm {m \, s^{-2} } .
The $\LaTeX$ code for \(\mathrm {m / s^2}\) is \mathrm {m / s^2} .
Also known as
The metre per second squared is also seen referred to as the metre per second per second.
This logically arises as its definition as the acceleration that causes a change in velocity of $1$ metre per second over the course of $1$ second.
