# Is MTTF the same as MTBF?

Technically, MTBF should be used only in reference to a repairable item, while MTTF should be used for non-repairable items. However, MTBF is commonly used for both repairable and non-repairable items.

Consequently, what is MTTR MTTF and MTBF?

“Mean time between failures” or “MTBF” refers to the amount of time that elapses between one failure and the next. Mathematically, this is the sum of MTTF and MTTR, the total time required for a device to fail and that failure to be repaired.

Additionally, what does MTBF mean? mean time between failures

Also know, what is MTTF formula?

MTTF is calculated as the total hours of operation, divided by the total number of items being tracked. MTTF in this instance would be (8 + 10 + 12) / 3 = 10 hours.

How do you calculate mean time between failures?

The MTBF is calculated by taking the total time a piece of equipment is running (i.e. uptime) and dividing it by the number of breakdowns that occurred over the same period.
