How to convert FIT to MTTF in Python using UliEngineering

You can easily convert FIT (Failures In Time) to MTTF (Mean Time To Failure) using the UliEngineering Python library:

FIT_to_MTTF.py
from UliEngineering.Reliability.Conversion import *
from UliEngineering.EngineerIO import *

# Convert 100 FIT to MTTF
mttf = FIT_to_MTTF(100)
print(f"100 FIT = {format_value(mttf, 'h')}")

# Convert 1000 FIT to MTTF
mttf = FIT_to_MTTF(1000)
print(f"1000 FIT = {format_value(mttf, 'h')}")

Example output

FIT_to_MTTF_output.txt
100 FIT = 1.00e+06 h
1000 FIT = 1.00e+05 h

FIT represents failures per billion hours. The conversion uses the formula: $MTTF = \frac{10^9}{FIT}$ hours.
