Fuel Efficiency Formula:
| From: | To: |
The MPG (Miles Per Gallon) formula calculates a vehicle's fuel efficiency by dividing the distance traveled by the amount of fuel consumed. This measurement helps compare the fuel economy of different vehicles.
The calculator uses the MPG formula:
Where:
Explanation: This simple calculation provides the number of miles a vehicle can travel per gallon of fuel, which is a standard measure of fuel efficiency.
Details: Calculating MPG helps vehicle owners understand their fuel consumption patterns, estimate fuel costs for trips, and compare the efficiency of different vehicles or driving habits.
Tips: Enter the distance traveled in miles and the amount of fuel used in gallons. Both values must be positive numbers. For best accuracy, reset your trip meter 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 15-20 MPG is typical for trucks and SUVs. Electric vehicles use different efficiency measurements.
Q2: How can I improve my vehicle's MPG?
A: Regular maintenance, proper tire inflation, reducing unnecessary weight, and adopting efficient driving habits (smooth acceleration, maintaining steady speeds) can improve fuel efficiency.
Q3: Does MPG vary with driving conditions?
A: Yes, MPG is typically lower in city driving with frequent stops than highway driving. Weather conditions, terrain, and vehicle load also affect fuel efficiency.
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 common elsewhere. Higher MPG means better efficiency, while lower L/100km means better efficiency.
Q5: Why does my calculated MPG differ from the manufacturer's rating?
A: Manufacturer ratings are based on standardized tests that may not reflect real-world driving conditions, habits, vehicle maintenance, or fuel quality.
