Conversion Formulas:
- 1 CFM = 0.471947 dm³/s
- 1 dm³/s = 2.11888 CFM
This conversion accounts for:
- 1 cubic foot = 28.3168 cubic decimeters
- 1 minute = 60 seconds
What are CFM and dm³/s?
- CFM (Cubic Feet per Minute) measures how much air moves in a space every minute.
- dm³/s (Cubic Decimeters per Second) does the same but measures air per second using cubic decimeters (which equals a liter).
Example
For example, an air duct in a building moving 300 CFM. That means 300 cubic feet of air flows through it every minute. To find out how many cubic decimeters per second that is, we need to convert CFM to dm³/s.
Step-by-Step Calculation:
1. CFM To dm³/s
We will use this conversion: 1 CFM = 0.471947 dm³/s
Now, let’s convert 300 CFM to dm³/s:
Multiply the CFM value by the conversion factor: 300 CFM × 0.471947 dm³/s = 141.5841 dm³/s
Result: 300 CFM equals 141.58 dm³/s.
2. dm³/s to CFM
What if we want to convert 200 dm³/s back to CFM? We will use the reverse formula: 1 dm³/s = 1 / 0.471947 CFM
Divide the dm³/s value by the conversion factor: 200 dm³/s ÷ 0.471947 = 423.91 CFM
Result: 200 dm³/s is about 423.91 CFM.
