What SI units should be used for flow per area - ie to convert gpm per ft2 to SI units?

If your flow is in Volume/Time, e.g. m3/s, and it's given per area, e.g. m2, you come up with the flow speed. An appopiate unit would be m/s
Example:
If your flow is 6 cubic meters per second, and this is given for 2 square meters, the flow has a speed of 3 meters per second.
Now the conversion to SI:
1 gpm = 6.30902e-5 m3/s
1 ft2 = 0.092903 m2
So 1 gpm per ft2 would give a flow speed of 6.79098e-4 m/s (0.68 millimeter per second)
If you don't have a volumetric flow, use the density of the material to convert it.

Is there anyway to convert flow to pressure measurements Say like 10liters per minute of 100 percent oxygen to a PSI measurement or is it just impossible and I should give up?
Flow rate cannot be converted into pressure units. So, you should give up the idea.

How do you work a flow transmitter?
A device used to measure the flow of liquids in pipelines and convert the results into proportional electric signals that can be transmitted to distant receivers or controllers. a velocity over a known surface area is measured and then it can be converted to volumetric flowrate or mass flowrate if the density of the fluid is known.
The flow of electrons along a conductor is measured in metric units called?
amperes
Convert cubic meter of argon gas into liters per minute?
A cubic meter is a unit of volume, specifically 1,000 litres.Litres per minute is a unit of flow.Units of volume and units of flow do not correlate without some factor of time. The question is invalid. Please restate the question.

How can you convert btu to cfm?
No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)
How do you convert millimeter h2o into Cubic Feet per Minute?
You can't convert those units. Milimeters of water (mmH2O) is a unit of pressure equal to about 13.6 mmHg. Cubic feet per minute is a measure of fluid flow.
How do you convert KG per hr to scfm?
"kg/hr" means "kilograms per hour" and "scfm" means "standard cubic feet per minute"Since the units are not compatible, we cant convert to that unit. The time units are consistent, but "kg" and "scf" aren't. "kg" measures mass while "scf" measures volume.Another way to prove this is:"kg/hr" measures mass flow while "scfm" measures volume flow.
How do you convert water flow in litres per min to pressure in bar?
The relationship between pressure and flow is given by Bernoulli's law. In an idealized system, the speed increases with the square of the increase in pressure. The flow rate would be given by multiplying the area of the outflow by the speed.
How do you convert liquid velocity of a specific density to liters per second?
Multiply the velocity in cm/s by the cross section area of the flow in sq cm.
In what units is heat flow measured?
kilocalories or kilojoules
How to Convert cfm to kw?
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
How do you convert water fixture units to gpm?
A fixture unit is 1 cubic foot of water (7.48 gallons) If your using pumped drainage /soil system then for every GPM of flow rate one has to consider it as ONE FU
What units does an oxygen flow meter read in?
liters per minute
What is the formula to convert FPM to CFM?
If you know the FPM and you know the area of your flow say duct work (20"x20")...first convert your area 20*20=400 in2 to Ft220"*20" = 400in2 400in2/144 = 2.7777Ft2Now that you know the area in Ft2 you can use the equation [ FPM*area(ft2) = CFM ]if your FPM is 500 and we use the 20"x20" duct then500fpm * 2.777Ft2 = 1388.5 cfm
