<h2>Detailed Description</h2>
<p>The QAccelerometerReading class reports on linear acceleration along the X, Y and Z axes.</p>
<a name="qaccelerometerreading-units"></a>
<h4>QAccelerometerReading Units</h4>
<p>The scale of the values is meters per second squared. The axes are arranged as follows.</p>
<p class="centerAlign"><img src="images/sensors-coordinates2.jpg" alt="" /></p><p>A monoblock device sitting at rest, face up on a desk will experience a force of approximately 9.8 on the Z axis (ie. towards the roof). This is the proper acceleration the device experiences relative to freefall.</p>
