About the units
Liter per second (L/s)
The liter per second (L/s) is a unit of volumetric flow rate in the metric system. One liter per second equals 0.001 cubic meters per second (m³/s).
Cubic foot per minute (CFM)
The US unit for fan, blower and air-compressor flow; about 1.699 m³/h. One cubic foot per minute equals 0.0004719474432 cubic meters per second (m³/s).
