How it works
Every value is converted to kilograms with a fixed factor, then divided by the target unit’s kilograms-per-unit factor. The implemented factors include 1 lb = 0.45359237 kg, 1 oz = 0.028349523125 kg and 1 stone = 6.35029318 kg.
Assumptions & limits
- Uses defined conversion factors for metric and avoirdupois units; results are as precise as the input and stored factors.
- Accepts mass units only; it does not convert force or account for local gravity.
