Convert units.
Without doing the math.

Length, weight, temperature, volume, area, speed, data and fuel economy — including the Canadian favourite: L/100 km to MPG.

● Instant browser calculation
Note: conversions are calculated locally in your browser. Results are rounded for display. Fuel economy uses US MPG and UK/Imperial MPG as separate units because they are not the same.

Everyday conversions

Switch categories at the top, choose the units and type a value. The result updates immediately. Use the swap button when you want to reverse the conversion.

Fuel economy is backwards

L/100 km measures fuel used per distance, while MPG measures distance per fuel used. That means the relationship is reciprocal rather than a simple multiplier. This converter handles that automatically.
