Mass Flux Density Converter
Mass flux is the mass that flows through each unit of area every second: the mass flow rate divided by the cross-section it passes through. Its SI unit is the kilogram per second per square meter, kg/(s·m²). It is used for flows through pipes, heat exchangers and evaporating surfaces.
mass flux = ṁ / A = ρ * v, the density times the flow speed. Water (1,000 kg/m³) moving at 2 m/s has a mass flux of 2,000 kg/(s·m²).
How to convert mass flux units
Type a value into any field, and every other unit is calculated at once. For example, 2 kg/(s·m²):
-
In kg/(h·m²): multiply by 3,600.
2 * 3,600 = 7,200 kg/(h·m²) -
In lb/(h·ft²): multiply by 737.338.
2 * 737.338 = 1,474.7 lb/(h·ft²)

Mass flux units
-
Kilogram / second / meter² (kg/s/m²): The standard unit for Mass Flux Density, representing mass flow per unit area in one second, measured in kilogram per second per square meter.
Conversion Factor: 1 kg/s/m² = 1,000 g/s/m² -
Gram / second / meter² (g/s/m²): The mass of a substance passing through a unit area in one second, measured in grams per second per square meter.
Conversion Factor: 1 g/s/m² = 0.001 kg/s/m² -
Gram / second / centimeter² (g/s/cm²): Similar to the first unit, but the area is in square centimeters instead of square meters.
Conversion Factor: 1 g/s/cm² = 10 kg/s/m² -
Kilogram / hour / meter² (kg/h/m²): Mass passing through a unit area in one hour, measured in kilograms per hour per square meter.
Conversion Factor: 1 kg/h/m² = 0.00027778 kg/s/m² -
