What is the definition of scale factor?

The ratio that describes the error between a change in the output of a navigational sensor in response to a change in the input being measured.

For example, an acceleration sensor that has a scale factor of 0.1 % detecting an actual acceleration of 2 g (19.61 m/s2) may output a value of 19.63 m/s2. The smaller the scale factor, the less the error between the actual input and the resultant bias-corrected output from the sensor.
