Convert g/kWh to L/h Calculator

Convert g/kWh to L/h with power and fuel density. A direct redirect to one generic calculator was broader than this exact fuel-consumption slug.

L/h = g/kWh x kW / density(g/L).
g/kWh is specific consumption; L/h also needs load or output power.

Convert g/kWh to L/h Calculator

Quick answer

L/h = g/kWh x kW / fuel density(g/L). For diesel at 832 g/L, 220 g/kWh at 10 kW is about 2.644 L/h.

Examples

Specific use Power Density Fuel flow
220 g/kWh 10 kW 832 g/L 2.644231 L/h
250 g/kWh 50 kW 832 g/L 15.024038 L/h
300 g/kWh 5 kW 745 g/L 2.013423 L/h
210 g/kWh 100 kW 832 g/L 25.240385 L/h

Why power is required

g/kWh describes grams of fuel per kilowatt-hour of work. L/h describes volume per hour. The missing bridge is the actual kW output or load during that hour.

Common mistake

Do not compare g/kWh and L/h without load. Two engines with the same g/kWh can use different L/h if one is producing more kW.
