Examples

1. Converting a Standard Sedan's Fuel Economy

Car Buyer
Background
A buyer in Germany is looking to import a US-spec sedan rated at 30 MPG but needs to know its fuel consumption in liters per 100 kilometers to compare it with local models.
Problem
Convert 30 MPG to L/100km with standard four-decimal precision.
How to Use
Input 30 in the MPG field and set the decimal precision to 4.
Example Config
{
  "mpg": 30,
  "precision": 4
}
Outcome
The tool outputs a result of 7.8405 L/100km.

2. High-Precision Conversion for a Hybrid Vehicle

Automotive Journalist
Background
A journalist is writing a review comparing a new hybrid vehicle rated at 52 MPG against European competitors.
Problem
Convert 52 MPG to L/100km with high precision to show exact differences.
How to Use
Input 52 in the MPG field and set the decimal precision to 6.
Example Config
{
  "mpg": 52,
  "precision": 6
}

FAQ

What formula is used for the MPG to L/100km conversion?

The tool uses the standard conversion formula: L/100km = 235.214583 / MPG.

Does this tool support UK (Imperial) MPG?

No, this tool specifically converts US miles per gallon to liters per 100 kilometers.

Can I customize the number of decimal places in the output?

Yes, you can adjust the decimal precision setting from 0 up to 10 decimal places.

Why does a higher MPG result in a lower L/100km value?

MPG measures distance per unit of fuel, while L/100km measures fuel volume per distance; therefore, they are inversely proportional.

Is there a limit to the MPG value I can input?

You can input any positive number, though extremely low values close to zero will yield very high L/100km results.
