Можно легко преобразовать FIT (отказы за время) в MTTFd (среднее время до отказа в днях) с помощью библиотеки Python UliEngineering:
Σ
TechOverflow calculators:
You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button.

FIT_to_MTTFd_output.txt
100 FIT = 4.17e+04 d
1000 FIT = 4.17e+03 dMTTFd — это среднее время до отказа, выраженное в днях. Преобразование использует формулу: $MTTFd = \frac{10^9}{FIT \cdot 24 \cdot 60 \cdot 60}$ дней.
