Metre per second squared (m/s²)

The metre per second squared, denoted by the symbol m/s², is the derived unit of acceleration in the International System of Units (SI). It measures the change in velocity of one metre per second occurring over a one-second interval. Derived directly from the SI base units for length (metre) and time (second), it forms the foundational standard for acceleration across all physical sciences, engineering, and international calibration standards.
