燃油效率（体积）是传播的距离与所消耗的燃料量的比率，通常以每升公里（km/L）测量。
1 g/L = 1 kg/L
1 kg/L = 1 g/L
例子:
将15 克每升转换为每升公斤：
15 g/L = 15 kg/L
| 克每升 | 每升公斤 |
|---|---|
| 0.01 g/L | 0.01 kg/L |
| 0.1 g/L | 0.1 kg/L |
| 1 g/L | 1 kg/L |
| 2 g/L | 2 kg/L |
| 3 g/L | 3 kg/L |
| 5 g/L | 5 kg/L |
| 10 g/L | 10 kg/L |
| 20 g/L | 20 kg/L |
| 30 g/L | 30 kg/L |
| 40 g/L | 40 kg/L |
| 50 g/L | 50 kg/L |
| 60 g/L | 60 kg/L |
| 70 g/L | 70 kg/L |
| 80 g/L | 80 kg/L |
| 90 g/L | 90 kg/L |
| 100 g/L | 100 kg/L |
| 250 g/L | 250 kg/L |
| 500 g/L | 500 kg/L |
| 750 g/L | 750 kg/L |
| 1000 g/L | 1,000 kg/L |
| 10000 g/L | 10,000 kg/L |
| 100000 g/L | 100,000 kg/L |
