How to convert FIT to MTTFd in Python using UliEngineering

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

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

# Convert 100 FIT to MTTFd
mttfd = FIT_to_MTTFd(100)
print(f"100 FIT = {format_value(mttfd, 'd')}")

# Convert 1000 FIT to MTTFd
mttfd = FIT_to_MTTFd(1000)
print(f"1000 FIT = {format_value(mttfd, 'd')}")

Example output

FIT_to_MTTFd_output.txt
100 FIT = 4.17e+04 d
1000 FIT = 4.17e+03 d

MTTFd is the Mean Time To Failure expressed in days. The conversion uses the formula: $MTTFd = \frac{10^9}{FIT \cdot 24 \cdot 60 \cdot 60}$ days.
