How this calculator works
Core formula
converted value = input value * source-unit factor / target-unit factorThe calculator normalizes each measurement into a common base unit first, then converts that normalized value into the target unit so the same logic can support many conversion pairs.
- Fuel economy conversions use inverse formulas because liters per 100 km and miles per gallon move in opposite directions.
- Time-unit conversions for months and years use standard average calendar lengths for planning purposes.
