Km to Mpg Calculator

Formula

The formula to calculate the fuel efficiency (Mpg) from kilometers (Km) is:

\[ \text{Mpg} = \frac{\text{Km} \times 0.621371}{\text{G}} \]

Where:

\(\text{Mpg}\) is the fuel efficiency in miles per gallon
\(\text{Km}\) is the distance traveled in kilometers
\(\text{G}\) is the amount of fuel used in gallons
0.621371 is the conversion factor from kilometers to miles

What is Km to Mpg?

Km to Mpg (Kilometers to Miles per Gallon) is a conversion factor that measures fuel efficiency. It indicates how many miles a vehicle can travel per gallon of fuel when the distance is measured in kilometers. This conversion is commonly used in countries that use the metric system but still refer to fuel efficiency in terms of miles per gallon. The higher the Km/Mpg value, the more fuel-efficient the vehicle is.

Example Calculation

Let's assume the following values:

Kilometers (Km) = 100
Fuel Used (G) = 10 gallons

Using the formula to calculate the fuel efficiency (Mpg):

\[ \text{Mpg} = \frac{\text{Km} \times 0.621371}{\text{G}} = \frac{100 \times 0.621371}{10} = \frac{62.1371}{10} \approx 6.21 \text{ miles per gallon} \]

The fuel efficiency (Mpg) is approximately 6.21 miles per gallon.
