What is the base SI unit for mass flux density?

The primary reference unit for mass flux density in this converter is the Kilogram per Second-Sq. Meter (kg/(s·m²)). All 5 supported mass flux density units are anchored to this standard.

Are these mass flux density conversion factors verified?

Yes, all mass flux density conversion constants on UnitConvertersGo are verified against NIST Special Publication 811 and ISO/IEC 80000 international metrology standards.

Mass Flux Density Conversion Formulas

Use the following formulas to convert between kilograms per second-sq. meter, kilograms per hour-sq. meter, and grams per second-sq. centimeter.

Kilograms per Second-Sq. Meter to Kilograms per Hour-Sq. Meter

kg/(h·m²) = kg/(s·m²) × 3,600

Kilograms per Hour-Sq. Meter to Kilograms per Second-Sq. Meter

kg/(s·m²) = kg/(h·m²) × 0.00027777

Kilograms per Second-Sq. Meter to Grams per Second-Sq. Centimeter

g/(s·cm²) = kg/(s·m²) × 0.1

Example: Convert 10 Kilograms per Second-Sq. Meter (kg/(s·m²)) to Kilograms per Hour-Sq. Meter (kg/(h·m²))

1 kg/(s·m²) = 3,600 kg/(h·m²)

10 kg/(s·m²) × 3,600 = 36,000 kg/(h·m²)

All mass flux density conversions are anchored to the international SI base unit (Kilogram per Second-Sq. Meter) for full scientific and engineering accuracy.
