## How it calculates

The conversion between different fuel consumption units is based on specific mathematical relationships. Here are the primary formulas used for conversion:

1. From MPG (US) to L/100km: 
   L/100km = 235.214 ÷ MPG (US)

2. From MPG (UK) to L/100km: 
   L/100km = 282.481 ÷ MPG (UK)

3. From L/100km to km/L: 
   km/L = 100 ÷ L/100km

In these formulas, 'MPG' represents miles per gallon, 'L' represents liters, and 'km' represents kilometers. The first two formulas convert from MPG to L/100km, which is a common measure of fuel efficiency outside the US. The last formula converts L/100km to km/L, providing another perspective on fuel consumption. These calculations demonstrate the direct relationship between distance traveled and fuel used, allowing users to assess fuel efficiency across different standards.

## Who should use this

Fleet managers analyzing fuel efficiency across various vehicles, automotive engineers conducting performance assessments, and international travelers comparing fuel costs in different countries are specific use cases for this tool. Additionally, environmental researchers evaluating the carbon footprint of different transportation methods may find the conversions useful.

## Worked examples

Example 1: Convert 25 MPG (US) to L/100km. Using the formula: L/100km = 235.214 ÷ 25 = 9.40856. Therefore, 25 MPG (US) is approximately 9.41 L/100km.

Example 2: Convert 10 L/100km to km/L. Using the formula: km/L = 100 ÷ 10 = 10. This means that a vehicle consuming 10 liters of fuel for every 100 kilometers travels 10 km for each liter consumed.

Example 3: Convert 40 MPG (UK) to L/100km. Using the formula: L/100km = 282.481 ÷ 40 = 7.062025. Thus, 40 MPG (UK) is approximately 7.06 L/100km, indicating efficient fuel consumption for vehicles in the UK context.

## Limitations

This tool has several limitations. Firstly, the precision of the conversion may vary based on the rounding of decimal places; thus, outputs may not always reflect exact values. Secondly, the formulas assume standard conditions and do not account for variations in temperature, driving conditions, or vehicle type, which can affect fuel consumption. Thirdly, the tool does not incorporate alternative fuel sources, which may have different consumption metrics. Lastly, while the tool converts based on specific formulas, real-world driving conditions may lead to discrepancies between calculated and actual fuel efficiency.

## FAQs

**Q:** How do I convert from L/100km to MPG?


**A:** To convert L/100km to MPG (US), use the formula: MPG (US) = 235.214 ÷ L/100km. For example, if you have a fuel consumption of 8 L/100km, the conversion would be MPG (US) = 235.214 ÷ 8 = 29.40 MPG (US).


**Q:** What is the difference between MPG (US) and MPG (UK)?


**A:** MPG (US) measures fuel efficiency in miles per gallon based on the US gallon, which is approximately 3.785 liters, while MPG (UK) uses the imperial gallon, approximately 4.546 liters. This difference in gallon size affects the conversion rates between the two.


**Q:** Can I use this tool for vehicles that run on alternative fuels?


**A:** This tool is designed specifically for conventional fuel consumption units. Alternative fuels may require different metrics that are not encompassed in this tool’s current functionality.


**Q:** Are the conversion formulas applicable worldwide?


**A:** While the formulas are based on standard conversions, regional differences in driving conditions and fuel standards may impact actual fuel efficiency and should be considered when analyzing results.
