How to Convert km/L to MPG
This conversion is linear (a simple multiplication). Both units measure distance per unit of fuel, so they scale proportionally.
- MPG (US) = km/L × 2.35214583 (exact: 3.785411784 L/gal ÷ 1.609344 km/mi)
- MPG (UK) = km/L × 2.82480936 (exact: 4.54609 L/gal ÷ 1.609344 km/mi)
Applying the formula to 20 km/L: 20 × 2.3522 = 47.0 MPG (US).
