How to Convert FIT to MTBF
- 1). Note the value in FIT that you wish to convert to MTBF. Check that the value is given in failures per billion hours and write it down.
- 2). Divide 1,000,000,000 by the FIT value that you wrote down and note the result. For example, if the FIT value is 2,500, the result is 400,000 (see Reference 2, Sec.3.6, p.8-p.9).
- 3). Check your calculation. Record the result, which is the FIT value converted to MTBF, in hours.
