How This Converter Works
This mass flux density converter uses linear scaling — converting between units using multiplication factors based on the mass flux density relationship.
Step 1: Convert input value using the "From" unit's factor
Step 2: Convert to the "To" unit using the target unit's factor

Mass Flux Density Converter: Convert Mass Flux Units
Mass flow and mass flux density may sound similar, but they answer different questions. Mass flow tells you how much mass passes through a system per unit time.
Mass flux density tells you how much mass passes through a unit area per unit time. A Mass Flux Density Converter makes it easier to convert between these measurements.
The CalculatorKits tool supports units including kg/m²·s, g/cm²·s, lb/ft²·s, kg/cm²·s, and g/m²·s.

What Is Mass Flux Density?
Mass flux density measures mass transfer through a surface per unit area and time.
A common SI expression is:
kg/(m²·s)
The area component is what distinguishes mass flux density from ordinary mass flow rate.
For example, two systems could have the same total mass flow but different mass flux values if the flow passes through surfaces of different sizes.
How to Use the Converter
1. Enter the Value
Type the mass flux density value.
2. Select the From Unit
Choose the unit associated with your original measurement.
3. Select the To Unit
Choose the target unit.
4. Convert
The calculator immediately produces the result.
5. Review the Relationship
The CalculatorKits page displays the conversion factor and calculation.
Common Mass Flux Density Units
The tool includes units such as:
- kg/m²·s
- g/cm²·s
- lb/ft²·s
- kg/cm²·s
- g/m²·s
These combinations represent mass, area, and time.
Mass Flux vs Mass Flow
This distinction is essential.
Mass flow rate: mass per time.
Mass flux density: mass per area per time.
A pipe carrying 10 kg/s describes a mass flow rate.
A surface transferring a certain amount of material through each square meter per second describes mass flux density.
If you need mass per time without an area component, use the Flow Mass Converter.
Where Is Mass Flux Density Used?
Mass flux density appears in:
- Heat and mass transfer
- Chemical engineering
- Membrane systems
- Evaporation
- Filtration
- Fluid mechanics
- Environmental engineering
- Process engineering
It is especially relevant when the surface area through which transport occurs matters.
Example
CalculatorKits gives the relationship:
1 kg/m²·s = 10 g/cm²·s
This illustrates how changing the area unit can significantly change the numerical value while describing the same physical quantity.
Why Use a Mass Flux Unit Converter?
The combination of mass, area, and time makes manual conversions easy to get wrong.
You may need to convert kilograms to grams while simultaneously changing square meters to square centimeters.
A converter handles those factors together.
Limitations
The calculator converts existing mass flux density values.
It does not calculate mass transfer from experimental data or determine whether a process is physically feasible.
For critical engineering work, verify the result using the applicable standards or technical calculations.
Frequently Asked Questions
What is mass flux density?
It is mass transferred through a unit area per unit time.
What is a common SI unit?
kg/(m²·s).
Is mass flux the same as mass flow?
No. Mass flux includes area, while mass flow does not.
Can this tool calculate membrane flux?
It can convert a membrane flux value between supported units, but it does not determine the flux from membrane operating conditions.
Key Takeaways
