Units of Vibration

Hi all,
Does anyone know the units of vibration messages? Or how to convert these to hz?


According to http://ardupilot.org/copter/docs/common-measuring-vibration.html#vibe-dataflash-log-message the vibe messages are in m/s/s.

The default logging rate is not high enough for FFT into Hz. You need to enable batch processing of the IMU data. See here:

According to the source code VIBEs and CLIPs units are m/s/s and they’re generates from IMU values .
But Inertial Measurement Unit (IMU) is a combination of accelerometers, gyroscopes and magnetometers ant they have different units, but you can measure vibrate in hz as described in this link
