CFM To M3/hr Calculator

There are two common ways to measure airflow are CFM and cubic meters per hour. How to switch between them, it is important for things like heating, air conditioning, factories and more.

What is CFM?

CFM stands for cubic feet per minute. It shows how many cubic feet of air pass by each minute. America and others using the Imperial system often use CFM for HVAC airflow.

What is cubic meters per hour?

Cubic meters per hour shows how many cubic meters of air pass by in an hour. Places using the metric system commonly use this when talking about air movement in factories and nature.

Demystifying Flow Rates: CFM vs. m³/h

What’s the deal with CFM and m³/h? These units both measure airflow, but they’re used in different contexts. CFM stands for Cubic Feet per Minute, mostly used in the U.S. and Canada. On the other hand, m³/h (Cubic Meters per Hour) is more common in Europe and other parts of the world.

Unit	Where It’s Used
CFM	U.S., Canada
m³/h	Europe, Global

So, when do you use each? If you’re working with American HVAC systems, you’ll likely use CFM. If you’re dealing with international equipment or specifications, you may see m³/h.

The CFM to m³/h Formula

Let’s talk about the formula. To convert CFM to m³/h (or vice versa), you need a simple multiplier:

1 CFM = 1.699 m³/h
1 m³/h = 0.5886 CFM

Now, let’s break it down step by step.

Conversion	Formula
CFM to m³/h	CFM × 1.699
m³/h to CFM	m³/h × 0.5886

For example, if you have 500 CFM, multiply it by 1.699 to convert to m³/h. In reverse, divide your m³/h by 1.699 to find the equivalent CFM.

Putting CFM to m³/h Conversion to Work

Now that you know the formula, let’s apply it to real-world scenarios. Imagine you’re working with an air conditioning system that needs a flow rate of 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. You’ve got an air ventilation system rated at 1000 m³/h. What’s the CFM?

Example 2
Flow rate (m³/h)	1000 m³/h
Converted to CFM	588.6 CFM

Whether you’re managing an HVAC system or calculating airflow for a fan, these conversions are essential.

FAQs

Q: What’s the difference between CFM and m³/h?
A: CFM stands for Cubic Feet per Minute, and m³/h stands for Cubic Meters per Hour. CFM is mostly used in the U.S., while m³/h is more common internationally.

Q: How do I convert CFM to m³/h?
A: Multiply your CFM value by 1.699. For example, 500 CFM × 1.699 = 849.5 m³/h.

Q: How do I convert m³/h to CFM?
A: Divide your m³/h value by 1.699. For example, 1000 m³/h ÷ 1.699 = 588.6 CFM.

Q: Why do I need to convert between these units?
A: You might need to convert for international equipment, specifications, or just to understand airflow in different units.
