First you need to be familiar with the data that you are working with. Once this has been done, you can then use the following steps and formula;
Get the number of feet in a meter taking into account that 2.54cm equals one inch. This means that one foot is 30.48 cm. What this means is that one foot equals 12x2.54 which gives you a sum of 30.48 cm. Taking into account that there are 100 cm in 1 meter, you will divide the 100by your previous answer of 30.48 = 3.28 feet for each meter.
You will then need to identify how many cubic feet make a cubic meter. Here you will need to convert from linear to volumetric. In order to do so, you will need to find the cube for the conversion factor 3.28^3 = 35.31. So you can conclude there are 35.31 cubic feet of each cubic meter.
From the above, you will need to determine the ratio in order to convert from cm to CFM. Basic knowledge tells us that we have 60 second in every minute. We use this with point number two where we found that there are 35.31 cubic in a meter, multiply the two figures by and you get approximately 2,119 cm. Meaning that there are 2,119 unit for every CMF in the Air conditioner.
You will then be required to convert the above figure to its equivalent. For example, if you have been given a rate of 10, you will multiply it by 2,119 = 21,190CMF.
The following above mentioned steps the basis of calculating the CMF in any given air conditioning system. It is a formula that has been used and continues to be used to determine the CMF. It may appear complex in the beginning but once you master it then it will be easy for you to work with the systems.
Alternatively, you could also covert the CMF to cm. It is just a matter of reciprocating the ratio given in point 4 by multiplying it by 0.0004719.
