Fresh Air Exchange Flow Rate Conversion. (Update)

I'm guessing;

Cmh = cubic meters per hour

cfm = cubic feet per minute

m³/hr * 35.3ft³/m³ * hr/60minutes = ft³/minute

1 cmh = 0.5883 cfm
sample
19 cmh x 0.5883 = 11.1777 cfm
answer = 11 cfm
formula to convert cmh to cfm

1 cbm = 1.6990108
sample
30 cfm x 1.6990108 = 50.070324 cbm/cmh
answer = 50 cbm or cmh
