Enter the mass flow rate in kilograms per hour and select the fluid or material density to determine the equivalent volumetric flow rate in cubic meters per minute.
Quick Overview
kg/h to m³/min conversion changes a mass flow rate into a volumetric flow rate using density.
The formula is:
m³/min = kg/h ÷ (ρ × 60)
- Water: 1000 kg/m³
- Diesel fuel: 830 kg/m³
- Gasoline: 740 kg/m³
- Ethanol: 789 kg/m³
- Crude oil: 870 kg/m³
- Air: 1.2 kg/m³
For example, 1000 kg/h of water equals about 0.0167 m³/min.

kg/h to m³/min Formula
The following formula is used to convert a mass flow rate in kilograms per hour to a volumetric flow rate in cubic meters per minute.
m³/min = kg/h / (ρ × 60)
Variables:
- m³/min is the volumetric flow rate in cubic meters per minute
- kg/h is the mass flow rate in kilograms per hour
- ρ is the density of the fluid in kilograms per cubic meter
- 60 converts hours to minutes
To calculate the volumetric flow rate, divide the mass flow rate by the fluid density to obtain cubic meters per hour, then divide by 60 to convert the result to cubic meters per minute.
What is kg/h to m³/min Conversion?
kg/h to m³/min conversion is the process of changing a mass flow rate into a volumetric flow rate. Because volume depends on how dense a fluid is, the same mass flow can represent very different volumetric flow rates for water, fuel, oil, or air. This is why density is required whenever you convert between these two types of flow units.
In engineering, process control, pumping systems, and fluid handling applications, mass flow and volumetric flow are often used side by side. Converting between them allows you to compare specifications, interpret process data, and match equipment ratings expressed in different units.
How to Convert kg/h to m³/min?
The following steps outline how to convert kilograms per hour to cubic meters per minute.
- First, determine the mass flow rate in kilograms per hour (kg/h).
- Next, determine the fluid density in kilograms per cubic meter (kg/m³).
- Divide the mass flow rate by the density to convert from kg/h to m³/h.
- Finally, divide the result by 60 to convert from m³/h to m³/min.
- Check your answer using the calculator above.
Example Problem:
Use the following values as an example problem to test your knowledge.
Mass Flow Rate = 6000 kg/h
Fluid Density = 1000 kg/m³
m³/min = 6000 ÷ (1000 × 60) = 0.1 m³/min
kg/h to m³/min Conversion Table
The table below gives example conversions for a 1000 kg/h mass flow rate of several common fluids using the formula m³/min = kg/h ÷ (ρ × 60).
| Fluid | Typical Density ρ (kg/m³) | 1000 kg/h in m³/min |
|---|---|---|
| Water | 1000 | 0.0167 m³/min |
| Diesel Fuel | 830 | 0.0201 m³/min |
| Gasoline | 740 | 0.0225 m³/min |
| Ethanol | 789 | 0.0211 m³/min |
| Crude Oil | 870 | 0.0192 m³/min |
| Air (20°C, 1 atm) | 1.2 | 13.89 m³/min |
Some typical density values used in these conversions include water at approximately 1000 kg/m³, diesel fuel at 830 kg/m³, gasoline at 740 kg/m³, ethanol at 789 kg/m³, crude oil at 870 kg/m³, and air at about 1.2 kg/m³ under standard conditions. Always use the most accurate density available for your specific temperature and pressure when precision matters.
