About this mass flux density converter
Convert mass flux density units for fluid dynamics, membranes, drying operations, reactors, and heat or mass transfer calculations.
Mass flux density is mass flow rate divided by area, so it is especially useful when comparing flow through surfaces or cross sections.
Units covered
Mass flux units
kg/(s·m²), g/(s·cm²), mg/(s·cm²), lb/(s·ft²), and lb/(hr·ft²).
Lab to plant scale
Move between cm² lab data and ft² or m² process equipment units.
Area-aware flow
Useful where total mass flow depends on membrane, duct, or reactor area.
How to use it
- Enter the mass flux density value.
- Select the current unit and target unit.
- Use the result in membrane, reactor, drying, or transport calculations.
