The metre per second squared is the unit of acceleration in the International System of Units (SI). As a derived unit, it is composed from the SI base units of length, the metre, and time, the second. Its symbol is written in several forms as m/s², m·s⁻² or ms⁻², ${\tfrac {\operatorname {m} }{\operatorname {s} ^{2}}}$ , or less commonly, as (m/s)/s.^[1]

As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.
