Fuel consumption is the one conversion table that works backwards: more L/100km means worse economy, while more mpg means better. Converting between them therefore cannot be a simple factor — it goes through a reciprocal.
The table covers L/100km (metric standard), km/L (Japan), US mpg and UK mpg (an imperial gallon is 20% larger, so the same car reads ~20% higher in UK mpg), plus gallons per 100 miles.
Frequently asked questions
How do I convert L/100km to mpg?
Divide 235.215 by the L/100km value for US mpg (e.g. 8 L/100km ≈ 29.4 mpg US), or 282.481 for UK mpg.
Is a lower L/100km number better?
Yes — it means fewer liters burned per 100 km. For mpg the direction flips: higher is better.
中文说明
油耗是唯一一张"方向相反"的换算表:百公里油耗数值越大越费油,而 mpg 数值越大越省油。因此这两类单位之间不是简单的倍数关系,必须经过一次倒数换算。
表内涵盖百公里油耗 L/100km(公制标准)、每升公里数 km/L(日本常用)、美制 mpg 与英制 mpg(英制加仑大约大 20%,同一辆车在英制口径下数值也高约 20%),以及百英里耗油量。
常见问题
百公里油耗怎么换算成 mpg?
美制 mpg = 235.215 ÷ 百公里油耗(如 8L/100km ≈ 29.4 mpg US);英制则用 282.481 除。
百公里油耗是不是越低越好?
是——数值越低代表每 100 公里烧的油越少;而 mpg 恰好相反,数值越高越省油。
