Kilogram per Hour per Square Meter (kg/(h·m²))
Definition: A metric mass flux density unit that swaps the base unit's second for an hour, better matching the pace at which most industrial filtration and drying processes are actually monitored.
History: A natural SI multiple built once process engineers found that per-second figures for slow, continuous operations were inconveniently small fractions.
Current use: Common on membrane filtration and industrial dryer datasheets, where flux is tracked and reported per hour rather than per second.
Kilogram per Hour per Square Foot (kg/(h·ft²))
Definition: A mixed metric-customary mass flux density unit pairing the metric kilogram and hour with the US customary square foot, common where equipment is specified in feet but mass is tracked in kilograms.
History: Emerged from international equipment trade, where US-built process equipment rated in square feet is often operated and reported on using metric mass units.
Current use: Seen on some imported filtration and drying equipment specification sheets that blend metric and US customary units.

How Mass Flux Density Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to kilograms per second per square meter. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Kilogram per Hour per Square Meter → Kilogram per Hour per Square Foot: multiply by 9.2903047. For example, 1 kg/(h·m²) × 9.2903047 = 9.2903047 kg/(h·ft²).
Mass Flux Density vs. Mass Flow Rate
Mass flux density is a mass flow rate that has been normalized by the area it passes through: mass flux density = mass flow rate ÷ area. The site's separate Flow - Mass Converter covers the un-normalized total flow rate (e.g. kilograms per second, with no area involved) — the reading you would get straight off a mass flow meter. Dividing that total flow by the cross-sectional or membrane area it flows through is what turns it into a mass flux density.
Why Area Normalization Matters
A large filtration membrane will naturally pass more total mass per second than a small one, even if the small membrane is actually performing better per unit of surface. Normalizing by area removes that size bias, letting engineers compare a lab-scale membrane coupon directly against a full production membrane module, or benchmark competing filter designs of different sizes on equal footing.
Example
A mass flux density of 1 kg/(h·m²) equals 9.2903047 kg/(h·ft²). For scale, typical reverse-osmosis membranes operate around 0.01-0.03 kg/(s·m²) of permeate flux, while an industrial spray dryer's evaporation rate can run considerably higher per square meter of drying surface.
Frequently Asked Questions
How many Kilograms per Hour per Square Foot are in 1 Kilogram per Hour per Square Meter?
1 Kilogram per Hour per Square Meter (kg/(h·m²)) equals exactly 9.2903047 Kilograms per Hour per Square Foot (kg/(h·ft²)).
What is mass flux density used for?
Mass flux density is used to quantify how fast material moves through a unit area — most commonly membrane permeation rates in reverse-osmosis and ultrafiltration systems, evaporation and drying rates off a material's surface, and mass-transport rates in chemical process design.
How is mass flux density different from mass flow rate?
Mass flow rate is the total mass moving per unit time (e.g. kilograms per second), with no reference to area. Mass flux density divides that flow rate by the area it passes through, giving a per-area rate that lets surfaces of different sizes be compared fairly.
How accurate are these conversions?
Every conversion factor used here is the exact, internationally recognized relationship between the underlying mass, time, and area units — results are limited only by floating-point display precision, not by rounded conversion constants.
Why are there only seven units on this page?
Mass flux density is a specialized quantity used mainly in membrane science and process engineering, so unlike broader categories such as length or weight, only a handful of unit combinations (metric and US customary, at second and hour time scales) see any real-world use.
