Overview

You typically use instances of NSUnitAcceleration to represent specific quantities of acceleration using the NSMeasurement class.

Acceleration

Acceleration is the rate of change of velocity. Acceleration can be expressed by SI derived units in terms of meters per second squared (m/s2).

The NSUnitAcceleration class defines its base unit as metersPerSecondSquared, and provides the following units, which are initialized using NSUnitConverterLinear converters with the specified coefficients:
