Converters
Unit converters
Convert between the units reliability and quality data arrives in — time bases, failure-rate units, and defect metrics — so figures from different sources can be compared.
Conventions used
The converters use the standard reliability conventions, so their results line up with the calculators:
Time
1 year = 8,760 h · 1 month = 730 h · 1 week = 168 hFailure rate
λ = 1 ÷ MTBF · FIT = λ (per hour) × 10⁹Defects
Yield = 1 − DPMO ÷ 10⁶ · sigma levels include the 1.5σ shift
