It is not clear what units you are referring to. The question software doesn't support many special characters, such as the slash (/), so you will need to edit your question and spell things out. Is the second one BTU per hour (BTU/hr)? For the life of me, I can't figure out what CMH is.
cmh is cubic meter per hour - m3/hr
CMH is a unit of flow rate (m3/hr or cubic metres per hour) A BTU is a British Thermal Unit, a unit of energy that is equal to around 1055 joules. You cant convert the two as they are a measure of different things, but changing BTU (or Btu) to joules will help standardise the calculations.
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.
about 8 or 9 maybe 10 or 11 could be 11 or 12 or neither

How do you convert fractions to what?
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
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
You can do it with two steps. first convert kmh to cmh (centimeter per hour) by duplicate it by 1000. then, convert the cmh to cms (centimeter per second) by divide it by 3600. in other words, you can just multiply the kmh by (10/36) and get the equal value with cms units.
Get it CMH Calculation
CMH Records was created in 1975.
CMH is a unit of flow rate (m3/hr or cubic metres per hour) A BTU is a British Thermal Unit, a unit of energy that is equal to around 1055 joules. You cant convert the two as they are a measure of different things, but changing BTU (or Btu) to joules will help standardise the calculations.
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.
12,000 btuh = 1 ton cooling.
1 watt = 3.413 Btuh 1 kW = 3413 Btuh
cfm is less than cmh by by 40% (approximately)
The general rule is for manufacturers to list the capacity of the units in thousands of BTUH. Hence 36,000 btuh divided by 12,000 btuh per ton = 3ton. lc
