Estimate fuel required and trip cost using US or Imperial MPG, L/100 km, or km/L. Compare vehicles, include repeated or round trips, split costs, or estimate theoretical range.
Distance is normalized to kilometers and fuel economy to liters per kilometer. Fuel required is distance multiplied by canonical consumption.
Fuel is converted to the selected price unit before multiplication, so liter, US gallon, and Imperial gallon prices remain distinct.
fuel liters = total distance km × liters per kmentered distance × trip-direction multiplier × trip countfuel in price unit × price per unittotal trip cost ÷ peopleavailable fuel liters ÷ liters per km300 miles at 30 US MPG requires 10 US gallons; at $3.50/gallon fuel costs $35.
500 km at 8 L/100 km requires 40 L; at 1.70 per liter fuel costs 68 in the selected currency.
A 150-mile one-way route marked round trip becomes 300 miles; at 25 MPG it requires 12 US gallons and costs $39 at $3.25/gallon.
A 20-mile one-way route, round trip, repeated five times totals 200 miles.
A $60 total split four ways costs $15 per person.
Ten US gallons at 30 US MPG provides a theoretical 300-mile range.
CalcRocket does not look up current gasoline, diesel, or other fuel prices.
US and Imperial MPG and gallon prices use different shared conversion constants.
Traffic, speed, weather, terrain, tires, load, idling, and driving style can change actual economy.
All economy inputs are converted through CalcRocket's shared fuel-economy converter into liters per kilometer.
Round trip doubles the entered one-way distance before multiplying by the number of identical trips.
Vehicles share the trip and entered fuel price. Results rank lowest fuel cost without making a subjective vehicle recommendation.
Tolls, parking, and other costs remain separate from fuel and are included only in total trip cost and passenger splits.
Calculate fuel required from distance and economy, then multiply by price per matching fuel unit.
Divide miles by MPG, or multiply kilometers by liters per kilometer.
Divide miles by MPG for gallons, then multiply by price per corresponding gallon.
Multiply kilometers by L/100 km and divide by 100.
It is kilometers traveled per liter; divide distance by km/L for liters.
Double the entered one-way distance.
Enter one-way distance, choose round trip, and enter the number of repeated trips.
Enter the number of people; total trip cost is divided equally.
Enter each vehicle's economy using any supported economy unit.
Divide fuel cost by total miles.
Reverse mode divides available fuel by canonical consumption.
No. US and Imperial gallons have different volumes.
No. Enter a price manually.
Not necessarily; real conditions can materially affect consumption.
