How to convert MTTF to FIT in Python using UliEngineering

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

MTTF_to_FIT.py

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

# Convert 1,000,000 hours to FIT
fit = MTTF_to_FIT("1000000h")
print(f"1,000,000 h = {fit:.0f} FIT")

# Convert 100,000 hours to FIT
fit = MTTF_to_FIT("100000h")
print(f"100,000 h = {fit:.0f} FIT")

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

# Convert 1,000,000 hours to FIT
fit = MTTF_to_FIT("1000000h")
print(f"1,000,000 h = {fit:.0f} FIT")

# Convert 100,000 hours to FIT
fit = MTTF_to_FIT("100000h")
print(f"100,000 h = {fit:.0f} FIT")

Example output

MTTF_to_FIT_output.txt

1,000,000 h = 100 FIT
100,000 h = 1000 FIT

1,000,000 h = 100 FIT
100,000 h = 1000 FIT

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