How to convert us miles per gallon to liters per 100 km
Use the formula below. ConvertPulse keeps the full conversion constant during calculation and rounds only the displayed result.
For example, 25 MPG equals 9.4086 L/100 km.

Understanding the result
Keep extra decimal places while you work, then round once at the end. For everyday use, two to four decimal places is usually enough. Scientific, engineering, and regulated work may require a specified precision or reference standard.
Fuel-economy conversions are reciprocal: a higher MPG value produces a lower L/100 km value. Zero cannot be converted because division by zero is undefined.
Why fuel-economy conversion is reciprocal
US MPG measures distance per fuel volume, while L/100 km measures fuel volume per distance. A higher MPG therefore produces a lower L/100 km result, and zero MPG cannot be converted because the reciprocal formula would divide by zero.
- Confirm that the source uses US MPG rather than imperial MPG.
- Use actual fill-up data for budgeting; rated values are comparison standards.
- Driving conditions, temperature, load, and maintenance affect real consumption.
