Mass Flow Rate Converter
Convert mass flow rates used in process, industrial and engineering calculations.
How to Use the Mass Flow Rate Converter
Enter a mass flow rate, choose the source unit and select the target unit for engineering and process calculations.
Practical Example
1 kg/s equals 60 kg/min and 3,600 kg/h.
Factors That Affect Mass Flow
Actual flow can vary with density, pressure, temperature, equipment condition and measurement method. The converter changes units only.
Frequently Asked Questions
What is mass flow rate?
It is the mass of material passing a point per unit time.
Is mass flow the same as volumetric flow?
No. They are related through density.
Can I convert kg/h to kg/s?
Yes. Divide kg/h by 3,600.
Understanding Mass Flow Rate Units
Mass flow rate describes how much mass passes a point per unit time and can be expressed in kg/s, kg/h, lb/s or similar units. Both the mass and time scales must be converted correctly.
The unit conversion does not determine flow from pipe size or pressure. Actual mass flow can depend on density, velocity, temperature and process conditions, so use a measured or calculated source value appropriate to the system.
Unit Relationship and Practical Context
Mass flow rate is mass transferred per unit time. Converting between kg/s, kg/h and similar units does not require density, but deriving mass flow from volumetric flow does; gas density can change substantially with pressure and temperature.
