Fuel Efficiency Formula:
| From: | To: |
MPG (miles per gallon) is a measurement of a vehicle's fuel efficiency, representing how many miles a vehicle can travel using one gallon of fuel. It's a standard metric used to compare the fuel economy of different vehicles.
The calculator uses the MPG formula:
Where:
Explanation: The formula calculates how efficiently a vehicle uses fuel by dividing the distance traveled by the amount of fuel consumed.
Details: Monitoring fuel efficiency helps vehicle owners track fuel consumption, estimate fuel costs, identify maintenance issues, and reduce environmental impact by optimizing fuel usage.
Tips: Enter the distance traveled in miles and the amount of fuel used in gallons. Both values must be positive numbers. For accurate results, reset your trip odometer when refueling and record the exact amount of fuel added.
Q1: What is considered good MPG?
A: Good MPG varies by vehicle type. Generally, 25-30 MPG is good for most cars, while 40+ MPG is excellent. SUVs and trucks typically have lower MPG ratings.
Q2: How can I improve my vehicle's MPG?
A: Regular maintenance, proper tire inflation, smooth driving, reducing excess weight, and avoiding excessive idling can improve fuel efficiency.
Q3: Does MPG vary with driving conditions?
A: Yes, MPG is affected by driving habits, traffic conditions, terrain, weather, and vehicle load. Highway driving typically yields better MPG than city driving.
Q4: What's the difference between MPG and L/100km?
A: MPG (miles per gallon) is used in the US, while L/100km (liters per 100 kilometers) is used in most other countries. Higher MPG means better fuel efficiency, while lower L/100km means better efficiency.
Q5: How accurate is this calculation?
A: The calculation is mathematically accurate based on your inputs. For the most precise measurement, use exact odometer readings and fuel pump measurements.
