MTTF hours conversion calculator

 

Overview

some computer equipment is given a Mean Time To Failure (MTTF) rating or MTBF (Mean Time Between Failure). This can be equipment such as:

  • keyboards
  • monitors
  • computers
  • hard drives
  • SSDs
  • optical drives (blu-ray, dvd-rom/dvd-ram/dvd-rw, cd-rw/cd-rom)
  • IC designs
  • Printed Circuit Board designs

This calculator allows you to find out what that MTTF translates into in years, months, etc. based on your hours usage during the week. this is why MTTF/MTBF is given in hours rather than in years, because calculated years/months can vary wildly.

integer numbers like hours MTTF, years, months, days, hours are integer64.

integer64 is unsigned and case insensitive. it ignores underscores(_). it can be hexadecimal (start with 0x), decimal (plain number or start with 0d), octal (start with 0, 0q, 0o), binary (start with 0b), and can be appended with SI units (:B :D :DB :H :HB :K :KB :M :MB :G :GB :T :TB :P :PB :E :EB :Z :ZB :Y :YB) or computer units (:Ki :KiB :Mi :MiB :Gi :GiB :Ti :TiB :Pi :PiB :Ei :EiB :Zi :ZiB :Yi :YiB) as a multiplier suffix. priority will be given to longer suffixes in a stream of printable characters.
