CFM to cfh [Cubic Foot per Hour] Calculator

Use our CFM to CFH calculator to convert your values, Cubic Feet per Minute (CFM) into Cubic Feet per Hour (CFH) efficiently.

How CFM Converts to CFH

Conversion from Cubic Feet per Minute (CFM) to Cubic Feet per Hour (CFH) is useful when working with air or gas flow rates. The rule is:

$$1 \text{ CFM} = 60 \text{ CFH}$$

Multiply the CFM value by 60 For CFM to CFH conversion.

$$CFH = CFM \times 60$$

Divide the CFH value by 60 for CFH to CFM conversion

$$CFM = CFH \div 60$$

Example

For example, an air conditioning system in a big office. If it moves 50 CFM, that means 50 cubic feet of air flows every minute. Now, if we look at an entire hour, the total airflow would be:

$$50 \times 60 = 3,000 \text{ CFH}$$

So, the system moves 3,000 cubic feet of air per hour.

Now, If you want to reverse the calculation. Suppose you need a system that circulates 18,000 CFH. To find the CFM:

$$18,000 \div 60 = 300 \text{ CFM}$$

This tells us that a system rated at 300 CFM will move 18,000 cubic feet of air per hour.

Conversion Steps

1. Example: Convert 25 CFM to CFH.

1. Use formula:
   $$CFH = 25 \times 60$$

    

2. Multiply:
   $$CFH = 1,500$$

    

Result: 25 CFM = 1,500 CFH

2. Example: Convert 12,000 CFH to CFM.

1. Use formula:
   $$CFM = 12,000 \div 60$$

    

2. Divide:
   $$CFM = 200$$

    

Result: 12,000 CFH = 200 CFM

Remember That:

✅ To convert CFM to CFH, multiply by 60.
✅ To convert CFH to CFM, divide by 60.
