Fuel Efficiency Converter

Convert vehicle fuel economy between km/L, US MPG, Imperial UK MPG, and L/100km.

Quick Answer & Summary

A fuel efficiency converter translates vehicle gas mileage across km/L, US MPG, Imperial MPG, and L/100km. To convert US MPG to km/L, divide by 2.352. To convert US MPG to L/100km, calculate 235.215 / MPG. 30 US MPG equals 12.75 km/L (7.84 L/100km).

Fuel Economy Mathematical Formulas
MPG (US) = km/L × 2.35215 | L/100km = 235.215 / MPG (US) | 1 MPG (Imp) = 1.20095 MPG (US)

Accounts for both direct distance-per-volume ratios (MPG, km/L) and inverse volume-per-distance metrics (L/100km).

Result

2.3521458333

1 km/L = 2.3521458333 mi/gal (US)
