公式
## How to Convert MPG to L/100km ### Formula **L/100km = 235.215 / MPG** This conversion uses the relationship: 1 US gallon = 3.78541 liters and 1 mile = 1.60934 km. The constant 235.215 comes from (100 * 3.78541) / 1.60934. Note that MPG and L/100km have an inverse relationship: higher MPG means lower L/100km. ### Key Difference MPG measures distance per fuel unit (higher is better). L/100km measures fuel per distance unit (lower is better). This inverse relationship means the conversion is a division, not a multiplication.
计算示例
Convert 30 MPG (US) to L/100km.
- 01Apply the reciprocal formula: L/100km = 235.215 / MPG
- 02L/100km = 235.215 / 30 = 7.84 L/100km
- 03Also: km/L = 30 * 0.425144 = 12.75 km/L
常见问题
Why is the conversion a division and not a multiplication?
MPG measures distance per fuel unit while L/100km measures fuel per distance unit. These are reciprocal measures, so the conversion involves dividing a constant by the MPG value rather than multiplying.
Is US MPG the same as UK MPG?
No. The US gallon (3.785 L) is smaller than the Imperial gallon (4.546 L). A car rated at 30 US MPG would be rated at approximately 36 Imperial MPG. This converter uses US gallons.
What is a good L/100km value?
For a typical passenger car, under 6 L/100km is excellent, 6-8 is good, 8-10 is average, and over 10 is below average. Hybrids can achieve 4-5 L/100km and EVs effectively achieve 0.
