Subject: [PATCH] iio: hid-sensors: Fix unit conversion
Date: Sun, 4 May 2014 18:02:00 -0700 [thread overview]
Message-ID: <1399251720-8158-1-git-send-email-srinivas.pandruvada@linux.intel.com> (raw)
When no units are specified the default units are milli-gauss. So
need to divide by 1000 to get iio default of Gauss.
Similarly the default units conversion from degrees to radians.
