thanks Yani
but I don't understand why you are telling me that I have to scale the
result, because in the example sensors.conf it's written :

chip "bmc-*"
#
# You should not need compute lines here, the driver will
# do all the conversions.

So I don't need to scale anything with thic bmc chip, no ?
