Konversikan antara mpg, L/100 km, dan km/L untuk galon AS dan Inggris: L/100 km = 235.215 ÷ US mpg atau 282.481 ÷ UK mpg.
Diperbarui Contoh terverifikasi: 4
30 mpg (US) kira-kira sama dengan 7.840486 L/100 km. Satu satuan menyatakan bahan bakar per jarak dan yang lain jarak per bahan bakar, sehingga angka lebih besar pada satu satuan berarti angka lebih kecil pada satuan lainnya.
| Satuan | Nilai | Definisi |
|---|---|---|
| kilometer per liter (km/L) | 12.75431 | Satuan dasar |
| liter per 100 km (L/100 km) | 7.840486 | km/L = 100 ÷ (L/100 km), tepat |
| mil per galon AS (mpg (US)) | 30 | 1 mpg (US) = 1.609344/3.785411784 km/L, tepat |
| mil per galon imperial (mpg (UK)) | 36.0285 | 1 mpg (UK) = 1.609344/4.54609 km/L, tepat |
1 mpg (US) = 1.609344/3.785411784 km/L, tepat
km/L = 100 ÷ (L/100 km), tepat
L/100 km mengukur bahan bakar yang dipakai per jarak; mpg (US) mengukur jarak per satuan bahan bakar. Keduanya berbanding terbalik: hasil kalinya selalu 235.2146, sehingga menggandakan salah satunya membuat yang lain menjadi separuh.
Kedua satuan didefinisikan secara eksak, tetapi nilai hasil konversi merupakan desimal berulang; nilainya ditampilkan dengan 12 angka penting.
Fuel economy comes in two shapes. Miles per gallon and kilometres per litre measure distance per unit of fuel; litres per 100 km measures fuel per distance. The two are reciprocals, so L/100 km = 100 ÷ (km/L), and a US mpg figure converts as L/100 km = 235.215 ÷ mpg.
The default converts 30 US mpg to 7.84 L/100 km. Comparing cars across markets is the usual reason: the US quotes mpg with a 3.785 L gallon, the UK quotes mpg with a 4.546 L gallon while selling fuel by the litre, most of Europe uses L/100 km and India uses km/L.
Because the scales are reciprocal, equal steps in mpg are not equal fuel savings: going from 10 to 20 mpg saves 5 gallons per 100 miles, while going from 30 to 50 mpg saves 1.33. The chart plots that curve.

Divide 235.215 by a US mpg figure, or 282.481 by a UK mpg figure. 30 US mpg is 7.84 L/100 km and 50 UK mpg is 5.65 L/100 km. The constants are 100 × 3.785411784 ÷ 1.609344 and 100 × 4.54609 ÷ 1.609344, built from the exact gallon and mile.
Because the imperial gallon is 20% larger: 4.54609 L against 3.785411784 L. A car doing 40 mpg on UK figures does 33.3 mpg in US gallons, and 40 US mpg is 48.0 UK mpg. Both describe the same fuel use; 40 UK mpg is 7.06 L/100 km.
Because fuel used is distance divided by mpg. Over 100 miles, 10 mpg burns 10 gallons and 20 mpg burns 5, a saving of 5; 30 mpg burns 3.33 and 50 mpg burns 2, a saving of 1.33. Larrick and Soll called this the “MPG illusion” (Science, 2008); L/100 km avoids it because it measures fuel directly.
Divide 100 by the km/L figure: 20 km/L is 5 L/100 km and 12.5 km/L is 8 L/100 km. At 10 km/L the two numbers are equal. To go from km/L to US mpg, multiply by 2.35215, so 15 km/L is 35.3 US mpg.
Yes. L/100 km counts fuel used, so a smaller number means less fuel: 5 L/100 km is twice as economical as 10 L/100 km. With mpg and km/L a larger number is better. The product of the two stays fixed, 235.215 for L/100 km and US mpg, which is why one falls as the other rises.
Akurasi bergantung pada masukan dan asumsi metode. Aritmetika desimal memakai 50 digit signifikan, tetapi perkiraan, metode numerik dan data sumber bisa kurang presisi; pembulatan yang ditampilkan tidak menghilangkan batasan itu. Contoh penyelesaian yang diperiksa dengan sumber independen: 4. Misalnya, “30 mpg (US) in L/100 km” diperiksa dengan 100 ÷ (30 × 1.609344 km / 3.785411784 L) = 112903/14400 (Python 3.8 fractions from the legal definitions).
