Select the "from" unit in the left column and  follow the row until the "to" unit column. 

  • gpm = gallons per minute, gpd = gallons per day, cfm = cubic feet per minute

Example - Convert from m3/h to Imperial gallons per minute (gpm)

Volume flow in m3/h must be multiplied with

3.67

to convert to Imp gpm.

Alternatively use the online fluid flow calculator above.
