 All the MEMS drivers in stm32duino repositories have the same units when returning physical (scaled) values:
 
-    - mg for accelerometer (thousandth of 1g that is 9.81 m/s^2)
+    - mg for accelerometer (thousandth of g, 1g is 9.81 m/s^2)
     - mdps for gyroscope (thousandth of degree/s)
     - mgauss for magnetometer (thousandth of gauss)
 
-Readings can be obtained either as raw (unscaled) ```uint16_t``` values from the ```XXX_GetAxesRaw``` functions, or as physical (scaled) ```uint32_t``` values from the ```XXX_GetAxes``` functions, where ```XXX``` is eithet ```ACC``` or ```GYRO```. The factor to use for scaling from a raw to a physical value is from the ```XXX_GetSensitivity``` functions.

The factor to use for scaling from a raw to a physical value is obtained from the ```XXX_GetSensitivity``` functions.
 
 For example, to convert the raw acceleration reading to float m/s^2, the following can be done:
 
 ```cpp
 int16_t acc_raw[3];
-float acc_g[3];
+float acc_ms2[3];
 float acc_sensitivity;
 
 AccGyr.ACC_GetAxesRaw(acc_raw);
 AccGyr.ACC_GetSensitivity(&acc_sensitivity);
 
-acc_g[0] = ((float)acc_raw[0] * acc_sensitivity) / 1000.0f * 9.81f;
-acc_g[1] = ((float)acc_raw[1] * acc_sensitivity) / 1000.0f * 9.81f;
-acc_g[2] = ((float)acc_raw[2] * acc_sensitivity) / 1000.0f * 9.81f;
+acc_ms2[0] = ((float)acc_raw[0] * acc_sensitivity) / 1000.0f * 9.81f;
