How to Convert Fuel Economy Units

Converting between different fuel economy units is crucial for comparing vehicle efficiency across different countries and standards. This calculator simplifies the process by using standard conversion factors.

What is the Formula?

The general formula for fuel economy conversion is:

\[ \text{Result} = \frac{\text{Output Unit Factor}}{\frac{\text{Input Unit Factor}}{\text{Input Value}}} \]

Where:

• Input Value is the fuel economy value you want to convert
• Input Unit Factor is the factor to convert the input unit to L/100km
• Output Unit Factor is the factor to convert L/100km to the desired output unit

What are the calculation steps?

1. Identify the input fuel economy value and unit
2. Determine the conversion factor to L/100km for the input unit
3. Convert the input value to L/100km
4. Determine the conversion factor from L/100km to the desired output unit
5. Convert the L/100km value to the final result

Example Calculation

Let's convert 30 MPG (US) to L/100km:

Step 1: Identify inputs

Input Value = 30 MPG (US)

Input Unit Factor (MPG to L/100km) = 235.214583

Output Unit Factor (L/100km to L/100km) = 1

Step 2: Apply the formula

\[ \text{Result} = \frac{1}{\frac{235.214583}{30}} \approx 7.84 \text{ L/100km} \]

Therefore, 30 MPG (US) is approximately equal to 7.84 L/100km.

Inverse Relationship between L/100km and Other Units

It's important to note that L/100km has an inverse relationship with other fuel economy units like MPG and km/L. This means:

• When L/100km increases, MPG and km/L decrease
• When L/100km decreases, MPG and km/L increase

This inverse relationship is due to L/100km measuring fuel consumption (higher values indicate less efficiency), while MPG and km/L measure fuel efficiency (higher values indicate more efficiency).

Diagram of Fuel Economy Conversion

The following diagram illustrates the concept of fuel economy conversion and the inverse relationship:

This diagram shows the relationship between MPG (US) and L/100km. The height of each bar represents the relative fuel consumption, with taller bars indicating higher consumption (lower efficiency). Note how the L/100km bar is shorter, reflecting the inverse relationship with MPG.
