Flow, pressure and temperature converter
Quick conversions between the flow, pressure and temperature units that appear on water treatment specifications and datasheets.

Formula used
1 m3/h = 16.667 L/min = 0.2778 L/s
1 US gallon = 3.785 L
1 bar = 100 kPa = 14.504 psi = 10.197 m head (water, 4 °C)
°F = °C × 1.8 + 32 · K = °C + 273.15
- GPM
- US gallons per minute
- GPD
- US gallons per day
- m head
- metres of water column
US gallons throughout (membrane datasheets quote GPD in US gallons). Head conversion assumes fresh water at 4 °C; brines and hot water differ slightly with density.
