gram per square metre per second

Mass fluxexact by definition

One gram per square metre per second, a thousandth of the SI unit. It is the working unit of fire engineering, where fuel mass burning fluxes fall in a convenient single-digit to tens range — a liquid pool fire typically runs a few tens of grams per square metre per second.

Watch out: Do not read it as grams per square metre, which is a paper and textile weight and carries no time at all. The per-second is doing essential work.
