What is CFM and CMH?
The cubic feet per minute (cfm) and the cubic meter per hour (cmh) are the units of volumetric capacity. CMH is important to consider when purchasing a new HVAC unit or evaluating the effectiveness of your current cooling system.
How do you convert cfm?
How do you convert m3/hr to CFM? Example: An air purifier can produce an airflow of 200 meter cube per hour. That converts to 200/1.699 = 118 CFM….Meter Cube Per Hour To CFM Conversion Chart.
| Meter Cube Per Hour (m3/hr) | CFM |
|---|---|
| How many CFM is 2000 m3/hr? | 1177.2 CFM |
How do you convert m3h to CFM?
The SI unit can easily be converted to cubic feet per minute (CFM): One m³/h is ~0.589 CFM and one CFM is ~1.699 m³/h.

How do you calculate CMH?
The value of the CMH statistic M is 4.62 (cell I9) as calculated by the formula =(ABS(B7-H7)-0.5)^2/I7.
How do you calculate CMH airflow?
How to Calculate the CFM of a Room
- Measure the room’s width and length.
- Multiply the three measurements from step 1 to determine the cubic footage of the room.
- Multiply the cubic volume of the room by the number of times you want the air to turn over or exchange in an hour.
How do you calculate CFM?
CFM = (fpm * area), where fpm is the feet per minute. To find the cubic feet per minute, substitute the FPM value with the area after the area is squared.
How do you convert CFM to kg cm2?
Basic Conversions
- 1 HP = 0.735 KW.
- 1 CFM = 28.238 LPM.
- 1 Kg/cm2 = 14.223 PSI.
- 1 MPa = 10 Bar.
- 1 Bar = 1.0193 Kg/cm2.
- 1 Kg = 2.205 Lbs.
How do you calculate CMH of a fan?
Define the terms in the general centrifugal fan formula and rearrange them to use the formula to solve for the higher air flow: CFM 1/CFM 2 = RPM 1/RPM 2 x (D1/D2)^3 (cubed). The (D1/D2)^3 is 1, since the impeller diameter stays the same, so CFM 2 = CFM 1 x (RPM 2/RPM 1).
How do you convert lh to ls?
L/h↔L/s 1 L/s = 3600 L/h.
What does m3 HR mean?
cubic meters per hour
m3/hr means cubic meters per hour.
How do you calculate HVAC cfm?
The calculation for CFM involves dividing the total volume of the space by the air exchange interval. To calculate room volume, you measure its length, width and height in feet and multiply these. Dividing this number by the change rate gives the required airflow in CFM.
What is the relationship between CFM and CMH?
The relationship between cubic feet per minute or cfm and cubic meter per hour or cmh is that there are approximately 0.59 cfm in 1 cmh. Similarly, 1 cfm is equal to approximately 1.7 cmh. How do you convert CFM to CMH?
