Indeed, it is important to convert between different measuring units when measuring air movement. You might need to convert two common units cubic meters per hour (cmh) and cubic feet per minute (cfm)
Cubic meters per hour tells you the amount of air in cubic meters going by per hour.
Cubic feet per minute tells you the amount of air in cubic feet going by per minute.
Cubic Meters per Hour (cmh) to Cubic Feet per Minute (cfm) Converter
What is cmh?
Cubic meters per hour is a metric unit used to measure air flow. It’s used for heating, air conditioning and factories where airflow needs precise counting.
What is cfm?
Cubic feet per minute is an imperial unit used to measure air flow per minute. America and other imperial countries often use it to count airflow.
Conversion Formula
To convert between cmh and cfm, use this formula:
cfm=cmh×0.588578
Demystifying Flow Rates: CFM vs. m³/h
What’s the difference between CFM and m³/h?
CFM stands for Cubic Feet per Minute and measures the volume of air that moves each minute. It’s mostly used in the U.S. and Canada. On the flip side, m³/h or Cubic Meters per Hour measures air volume per hour and is common in Europe and other parts of the world.
Unit | Where It’s Used |
---|---|
CFM (Cubic Feet/Min) | U.S., Canada |
m³/h (Cubic Meters/Hour) | Europe, Global |
When should you use each? If you’re working with American systems like HVAC units, you’ll likely see CFM. If you’re handling international specs, you’ll run into m³/h.
So, if you know your flow rate in CFM and want to switch to m³/h, multiply it by 1.699. For the reverse, divide your m³/h by 1.699 to get the CFM.
Conversion | Formula |
---|---|
CFM to m³/h | CFM × 1.699 |
m³/h to CFM | m³/h × 0.5886 |
For example, if you have 400 CFM, multiplying by 1.699 gives you 679.6 m³/h.
Practical Examples
Now that you’ve got the formula, let’s see how it works in real life. Imagine you’re dealing with a ventilation system that’s rated at 600 CFM. How do you convert that to m³/h?
Example 1 | |
---|---|
Flow rate (CFM) | 600 CFM |
Converted to m³/h | 1019.4 m³/h |
Now, let’s flip it around. If you’re working with an air purifier that has a flow rate of 1000 m³/h, what’s the CFM?
Example 2 | |
---|---|
Flow rate (m³/h) | 1000 m³/h |
Converted to CFM | 588.6 CFM |
See how easy it is? Whether you’re working with air conditioners or fans, this conversion helps you understand airflow no matter the unit.

Frequently Asked Questions
Q: What’s the difference between CFM and m³/h?
A: CFM measures how much air moves in a minute, while m³/h measures it per hour. CFM is used in the U.S., and m³/h is common in Europe.
Q: How do I convert CFM to m³/h?
A: Just multiply your CFM by 1.699. For example, 500 CFM × 1.699 equals 849.5 m³/h.
Q: How do I convert m³/h to CFM?
A: Divide your m³/h by 1.699. So, if you have 1500 m³/h, divide it by 1.699 to get 882.87 CFM.
Q: Why do I need to convert between CFM and m³/h?
A: You might work with international equipment or need to compare specs. Converting helps you understand airflow no matter the unit.
