The conversion of 100 kilometers to miles per gallon results in approximately 52.14 mpg.
This calculation is based on converting kilometers to miles (1 km ≈ 0.621371 miles) and considering fuel efficiency. Since miles per gallon measures miles traveled per gallon of fuel, we first find miles from kilometers then divide by fuel volume, assuming 1 gallon.
Conversion Result
100 kilometers is about 62.1371 miles. If you consider a vehicle that consumes 1 gallon of fuel to travel these miles, then the vehicle’s fuel efficiency is roughly 52.14 mpg.

Conversion Formula
The formula to convert kilometers to mpg multiplies kilometers by 0.621371 to get miles, then divides by 3.78541 (liters per gallon in US). This works because miles per gallon equals miles divided by gallons, and converting units accordingly yields accurate results.
For example, 100 km * 0.621371 = 62.1371 miles. Dividing 62.1371 miles by 3.78541 liters gives approximately 16.42 miles per liter, but since mpg uses gallons, we convert liters to gallons: 1 gallon = 3.78541 liters. So, 16.42 miles/liter * 3.78541 = 62.1371 miles/1 gallon, which simplifies to 52.14 mpg.
Conversion Example
- Convert 150 kilometers:
- 150 km * 0.621371 = 93.20565 miles
- Divide by 3.78541: 93.20565 / 3.78541 ≈ 24.63 mpg
- Convert 80 kilometers:
- 80 km * 0.621371 = 49.70968 miles
- Divide by 3.78541: 49.70968 / 3.78541 ≈ 13.14 mpg
- Convert 200 kilometers:
- 200 km * 0.621371 = 124.274 miles
- Divide by 3.78541: 124.274 / 3.78541 ≈ 32.8 mpg

Conversion Definitions
Kilometers is a metric unit measuring distance, where 1 kilometer equals 1000 meters, used worldwide for most distances outside the US and UK. It is part of the International System of Units, representing length or travel distance in various applications.
MPG (miles per gallon) measures vehicle fuel efficiency, indicating how many miles a vehicle can travel on one gallon of fuel. It helps compare fuel consumption, with higher mpg showing better efficiency, often used in automotive and environmental assessments.
Conversion FAQs
Why is converting kilometers to mpg important?
Converting kilometers to mpg helps drivers understand their vehicle’s fuel efficiency in familiar units, especially when traveling or purchasing vehicles in regions using metric units. It allows better comparison with local fuel economy standards.
Can I convert any distance from km to mpg directly?
No, because km measures distance, while mpg measures efficiency. To convert km to mpg, you need to know the fuel consumed over that distance. The conversion involves calculating miles traveled and dividing by gallons used, not just the distance alone.
What assumptions are made in this conversion?
The calculation assumes a US gallon (3.78541 liters) and that the vehicle’s fuel consumption is proportional, with no other factors like driving conditions affecting the result. It also presumes the distance is traveled on a full tank with consistent fuel usage.
How accurate is the conversion for real-world driving?
The conversion provides an estimate based on standard unit conversions and ideal conditions. Actual fuel efficiency can vary due to driving habits, vehicle condition, terrain, and other factors, so the real-world mpg might differ from calculated values.
Is there a way to convert km/l to mpg?
Yes, to convert km/l to mpg, multiply km/l by 2.352. This conversion accounts for changing units from kilometers per liter to miles per gallon, since 1 km/l ≈ 2.352 mpg.
