You can't.
Pascals (pa) area messurement of pressure. CFM (cubic feet per minute) is a rate of flow. However, there is a device called a manometer which is used to measure either pressure(in pascals) or air flow in(in cubic feet). Most commonly used for blower door tests.
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
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
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.
1 bar = 105 Pascals (Pa)
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
1 pa = ? CFM
Tr = cfm/400
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
divide by 60
1,000 cfm (feet3/min) is 0.4719474 m3/sec.
No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)
Cmh = cubic meters per hour cfm = cubic feet per minute m3/hr * 35.3ft3/m3 * hr/60minutes = ft3/minute So, 1 cmh = 0.5883 cfm

pa/b = (pa)1/b = bth root of (pa)
1kPA = 1000 Pa, so 207.9 Pa is 0.2079 kPa. (Am I missing something here?)
