Formula and assumptions

V (L) = q (L/h) × t (h); C = V × p; t (h) = Vtank/q

Enter measured or manufacturer L/hour for the actual load and fuel. No universal diesel coefficient is assumed. Excludes startup and variable loads.

STEP BY STEP

How to use generator fuel consumption calculator

  1. Check the input units and assumptions.
  2. Review the result and example.

IN PRACTICE

Example

5 L/h × 8 h = 40 L; 40 × 1.5 = 60; 100 L / 5 L/h = 20 h.

GOOD TO KNOW

How is this result calculated?

Fuel (L) = rate (L/h) × hours; cost = fuel × price/L; runtime (h) = usable tank liters / rate. Enter measured or manufacturer L/hour for the actual load and fuel. No universal diesel coefficient is assumed. Excludes startup and variable loads.
