Fuel Economy Converter - MPG to L/100 km

1. What is Fuel Economy Converter?

Definition: This converter transforms fuel economy values from miles per US gallon (mpg US) to miles per UK gallon (mpg UK), liters per 100 kilometers (L/100 km), and kilometers per liter (km/L).

Purpose: It is used in automotive and transportation contexts to convert fuel efficiency measurements for vehicles, aiding in comparisons across different regions and standards.

2. How Does the Converter Work?

The converter uses the following formulas:

Formulas:

Miles per UK Gallon: \[ \text{mpg UK} = \text{mpg US} \times 1.2010 \]
Liters per 100 Kilometers: \[ \text{L/100 km} = \frac{235.214583}{\text{mpg US}} \]
Kilometers per Liter: \[ \text{km/L} = \text{mpg US} \times 0.425143707 \]

Where:

\( \text{mpg US} \): Miles per US gallon
Conversion factors are derived from the relationships between US gallons, UK gallons, miles, kilometers, and liters.

Unit Conversions:

Fuel Economy:
- 1 mpg US = 1.201 mpg UK
- 1 mpg US = \( \frac{235.214583}{\text{mpg US}} \) L/100 km
- 1 mpg US = 0.425143707 km/L

Steps:

Enter the fuel economy value in miles per US gallon.
Validate the input to ensure it is positive.
Apply the conversion formulas to compute the fuel economy in each unit.
Display the results, using scientific notation for values less than 0.001, otherwise with 4 decimal places.

3. Importance of Fuel Economy Conversion

Converting fuel economy between different units is crucial for:

International Travel: Drivers can compare fuel efficiency in regions using different units (e.g., US vs. UK, or metric vs. imperial).
Vehicle Comparison: Allows consumers to compare the efficiency of vehicles rated in different standards.
Environmental Impact: Helps in calculating fuel consumption and emissions based on regional standards.

4. Using the Converter

Example: Convert 30 mpg US to other fuel economy units.

Enter the fuel economy, \( \text{mpg US} = 30 \).
The converter calculates:
- mpg UK: \( 30 \times 0.832674 = 24.9802 \)
- L/100 km: \( \frac{235.214583}{30} = 7.8405 \)
- km/L: \( 30 \times 0.425143707 = 12.7543 \)
The converter returns:
- Miles per UK Gallon: 24.9802
- Liters per 100 Kilometers: 7.8405
- Kilometers per Liter: 12.7543

Another Example: Convert 50 mpg US to other fuel economy units.

Enter the fuel economy, \( \text{mpg US} = 50 \).
The converter calculates:
- mpg UK: \( 50 \times 0.832674 = 41.6337 \)
- L/100 km: \( \frac{235.214583}{50} = 4.7043 \)
- km/L: \( 50 \times 0.425143707 = 21.2572 \)
The converter returns:
- Miles per UK Gallon: 41.6337
- Liters per 100 Kilometers: 4.7043
- Kilometers per Liter: 21.2572

5. Frequently Asked Questions (FAQ)

Q: What is the Fuel Economy Converter?
A: The Fuel Economy Converter transforms fuel economy values from miles per US gallon to miles per UK gallon, liters per 100 kilometers, and kilometers per liter.

Q: Why are there different fuel economy units?
A: Different regions use different units: mpg is common in the US and UK, while L/100 km and km/L are used in metric countries, requiring conversions for consistency.
