How to convert G to dbVrms

Abishek Devan

Hello Team,

We would like to measure the vibration using LIS2DW12 (3-axis MEMS accelerometer), from the LIS2DW12 we were getting units in 'g' or 'mg'.

Please let us know the possibility of converting g to dbVrms.

Best regards,

Abishek Devan

Welcome, @Abishek Devan​, to the community!

The value at the sensors is output in multiples of the acceleration due to gravity.

What is the relationship between this value and dbVrms, which is usually a logarithmic ratio of two voltages?

Regards
