    Question about failure rates and MTBF

    Is the failure rate the square root of the MTBF?
    I don't think so, but I would like someone to confirm this, please.

    Thank you,

    Just looking at the units:

    MTBF is measured in time (eg seconds)

    Failure rate would be fails/second or seconds/fail

    sqrt(MTBF) would be sqrt seconds (which doesn't make a lot of sense) and certainly not the same as fails/second or seconds/fail.

    So no (based solely on the units), failure rate is not the square root of MTBF.
