US MPG to L/100 km Converter Formula
The formula divides 235.215 by US MPG.
L/100 km = 235.215 ÷ US MPG
US MPG = 235.215 ÷ L/100 km
- 235.215
- = 100 × 3.785411784 L per US gallon ÷ 1.609344 km per mile
- US MPG
- = miles per US gallon (3.785 liters)
Worked Example
- A US-market sedan is rated 32 MPG combined.
- L/100 km = 235.215 ÷ 32 = 7.35 L/100 km.
- km/L = 100 ÷ 7.35 = 13.6 km/L.
- A Canadian rating of 6.5 L/100 km equals 235.215 ÷ 6.5 = 36.2 US MPG.
