How KG/hr to L/hr Works?
KG/hr to L/hr works by dividing the mass flow rate in kilograms per hour (kg/h) by the fluid density in kilograms per liter (kg/L). The converter accepts 7 mass flow units, including kg/s, kg/min, kg/h, t/h and lb/h, and returns 7 volume flow units, including L/h, L/min, m³/h, US gal/min (GPM) and barrels per day (bbl/day).

250 kg/h of diesel ÷ 0.832 kg/L = 300.48 L/h (5.01 L/min, 1.32 US GPM).
4 steps to use KG/hr to L/hr
Choose the direction: "Mass flow → Volume flow" or "Volume → Mass".
Select the fluid, including diesel, petrol, water and hydraulic oil, or enter a custom density.
Enter the mass flow rate and select the unit.
Read the volume flow rate and the time to fill a 20 L jerrycan, 208 L drum or 1,000 L IBC tote.
KG/hr to L/hr Formula
The KG/hr to L/hr formula is L/h = kg/h ÷ density, written as Qv = Qm ÷ ρ. The formula has 3 variables:
Qv (volume flow rate) is the result in liters per hour (L/h).
Qm (mass flow rate) is the input in kilograms per hour (kg/h).
ρ (rho, density) is the fluid density in kilograms per liter (kg/L).
Qv = Qm ÷ ρ
3 worked examples of the KG/hr to L/hr formula
100 kg/h of diesel ÷ 0.832 = 120.19 L/h.
1 kg/s of water = 3,600 kg/h ÷ 0.998 = 3,607.2 L/h.
2 t/h of petrol = 2,000 kg/h ÷ 0.745 = 2,684.56 L/h.
Kilograms per second (kg/s) multiply by 3,600 to give kg/h, and kilograms per minute (kg/min) multiply by 60.

What Is KG/hr to L/hr?
KG/hr to L/hr is a flow rate conversion that turns mass flow in kilograms per hour (kg/h) into volume flow in liters per hour (L/h).
Mass flow meters, including Coriolis meters, measure kg/h, and pumps, tanks and fuel gauges use L/h. Engine and generator data sheets list fuel consumption as mass flow in kg/h or g/kWh.
1 kg/h of water equals 1.002 L/h at 20 °C (68 °F).
1 kg/h of diesel equals 1.202 L/h at 15 °C (59 °F).
1 kg/s equals 3,600 kg/h and 216,000 kg/day.
What Are the Uses of KG/hr to L/hr?
There are 4 main uses of KG/hr to L/hr: generator fuel planning, boiler and burner sizing, coriolis meter checks and pipeline transfer.
Generator fuel planning: A 500 kVA generator burning 85 kg/h of diesel uses 102.2 L/h.
Boiler and burner sizing: Burners rated in kg/h of fuel oil convert to L/h for pump selection.
Coriolis meter checks: Process engineers compare Coriolis kg/h readings with tank level changes in L/h.
Pipeline transfer: A 30,000 L tanker unloads in 1 hour at 24,960 kg/h of diesel.
