You cannot since the two measure different things.
-- to convert the feet to inches, multiply by 12-- to convert the minute to second, divide by 60-- combining these operations, take (feet per minute) and multiply by (12/60) = 0.2
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
You can convert in w.c. to feet per minute and then convert fpm to CFM. FPm is 4005 times the square root of the pressure. So to convert 1 " w.c. to fpm its the square root of 1, which is 1 times 4005, which is 4005 fpm. Then you multiply the fpm by the area of the space the air is moving through. So if you have 1 " wc moving through a hole that's 1 square foot in area, that's 4005 cubic feet per minute.

'F' (feet / minute) x (1 minute / 60 seconds) = (F / 60) (feet - minute / minute - second) = F/60 ft/sec -- Take the number of feet per minute. -- Divide it by 60. -- The answer is the number of feet per second.
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.
You can MEASURE feet per minute. This measure is called velocity. Velocity is how far something has traveled divided by the time it takes to cover that distance. If you already know the velocity in miles per hour, you can convert to feet per minute by multiplying miles per hour by the fraction 5280 / 60, since there are 5280 feet in a mile and 60 minutes in an hour.

5280 feet minute
Cubic feet per minute x 28.3168 = liters per minute
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
You cannot without knowing the dimensions and shape.
Multiply meters per minute by 3.28 to get feet per minute.
Short for cubic feet per minute, a measurement of the velocity at which air flows into or out of a space.
You need to know the area of the pipe or duct. If you have that area, in square feet, V = Q/A where V = velocity (ft/minute in this case), Q = flowrate (cubic feet/minute in ths case), and A = area (square feet in this case). Then, you just have to apply conversions to get whatever units you want to present or use the answer in.
kpa = kilopascals is a measure of pressure. cfm = cubic feet per minte is a measure of the rate of flow. The two measure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
