About unit conversion
The converter transforms values through one base unit per category. SI, US and Imperial definitions remain distinct.
Temperature uses offsets; fuel consumption uses reciprocal relationships. Decimal storage units differ from binary units such as MB and MiB.
Currencies, time zones and mass-to-volume ingredient conversions are not included. Mathematical conversion does not assess physical plausibility.
