pound per square foot per second
One pound of material crossing one square foot every second, equal to 4.8824 kg/(m²·s). It appears in older North American fire and process literature, where burning rates and drying rates were tabulated in inch-pound units.
Watch out: The conversion is not a round number and there is no shortcut worth memorising. Note also that pounds per square foot without a time is a pressure — the psf that appears in wind and snow loading — and the two are entirely different quantities that read almost identically.
