Frequently Asked Questions

Is temperature handled correctly?

Yes — temperature uses affine conversions (°F has an offset of 32). Celsius, Fahrenheit, Kelvin, Rankine, Réaumur all supported.

L/100km is odd — higher means less efficient?

Correct — it is an inverse measure (volume per distance). The tool inverts correctly when converting between km/L or mpg and L/100km.

KB (decimal) vs KiB (binary)?

Both available. 1 KB = 1000 B. 1 KiB = 1024 B. Matters for file size vs disk capacity claims.
