How Fuel Consumption Calculator Works
This tool works by converting a planned distance into the fuel volume a vehicle needs, using MPG or L/100 km.
- Step 1
Enter the distance
Type the planned miles or kilometers.
- Step 2
Enter fuel economy
Type MPG, L/100 km, or km/L.
- Step 3
Calculate the fuel needed
The calculator divides miles by MPG or multiplies kilometers by L/100 km.
- Step 4
Read the volume
The calculator shows US gallons, imperial gallons, and liters needed.
Fuel Consumption Calculator Formula
The formula divides distance by MPG, or multiplies distance by L/100 km and divides by 100.
Fuel Needed (gal) = Miles ÷ MPG
Fuel Needed (L) = Kilometers × L/100 km ÷ 100
- Miles, Kilometers
- = planned distance
- MPG, L/100 km
- = fuel economy or consumption rating
Worked Example
- A driver plans 465 miles (748 km) in a 31 MPG (7.6 L/100 km) car.
- Fuel needed = 465 ÷ 31 = 15 US gallons.
- In liters = 15 × 3.785 = 56.8 liters; in imperial gallons = 12.5.
- A 14-gallon (53 L) tank needs one refuel on the way.
Fuel Consumption Calculator Conversion Table
The table lists liters needed for common distances in kilometers across consumption ratings.
| Distance (km / mi) | 5 L/100 km | 7 L/100 km | 9 L/100 km | 12 L/100 km | 15 L/100 km |
|---|---|---|---|---|---|
| 100 / 62 | 5.0 L | 7.0 L | 9.0 L | 12.0 L | 15.0 L |
| 250 / 155 | 12.5 L | 17.5 L | 22.5 L | 30.0 L | 37.5 L |
| 500 / 311 | 25.0 L | 35.0 L | 45.0 L | 60.0 L | 75.0 L |
| 750 / 466 | 37.5 L | 52.5 L | 67.5 L | 90.0 L | 112.5 L |
| 1,000 / 621 | 50.0 L | 70.0 L | 90.0 L | 120.0 L | 150.0 L |
| 1,500 / 932 | 75.0 L | 105.0 L | 135.0 L | 180.0 L | 225.0 L |
| 2,000 / 1,243 | 100.0 L | 140.0 L | 180.0 L | 240.0 L | 300.0 L |
What is a Fuel Consumption Calculator?
A Fuel Consumption Calculator is a planning tool that calculates the fuel volume needed to drive a given distance.
Fuel volume comes before fuel cost. Drivers need it to plan refuel stops, check tank capacity, carry fuel for remote travel, and order fuel for generators and equipment. The Fuel Consumption Calculator returns the volume in US gallons, imperial gallons, and liters.
Add 10% for headwinds, hills, and detours on remote routes with few stations.
What are the uses of a Fuel Consumption Calculator?
There are 4 main uses of the Fuel Consumption Calculator, including refuel planning, remote travel, and fuel orders.
Plan refuel stops
Compare fuel needed with tank capacity.
Prepare for remote travel
Carry enough reserve fuel on outback or desert routes.
Order bulk fuel
Estimate fuel deliveries for farm or site vehicles.
Feed cost calculations
Multiply volume by price for a trip budget.
