CFM to Cubic kilometers/sec [ km3/s ] Calculator
🔄 CFM ↔ km³/s Converter 🌍
Contents
📝 Conversion Formulas:
- 1 CFM = 4.71947 × 10-13 km³/s
- 1 km³/s = 2.11888 × 1012 CFM
🧮 This conversion accounts for:
- 1 cubic foot = 0.0283168 cubic meters
- 1 cubic kilometer = 1 × 109 cubic meters
- 1 minute = 60 seconds
- (0.0283168 ÷ 1e9) ÷ 60 = 4.71947 × 10-13 km³/s per CFM
| CFM | km³/s |
|---|---|
| 0 | 0 |
| 1 | 4.71947e-13 |
| 10 | 4.71947e-12 |
| 100 | 4.71947e-11 |
| 1000 | 4.71947e-10 |
Importance
For example, a climate scientist is studying how air moves around the world. All weather patterns are measured in Cubic Feet per Minute (CFM), but for big-picture calculations, he need to use Cubic Kilometers per Second (km³/s). To understand airflow across huge areas, he will need to convert between these two units.
To analyze planetary-scale air circulation, a climate scientist must convert between CFM and km³/s.
How To Convert A CFM Value To Cubic kilometers/sec
The standard conversion between Cubic Feet per Minute (CFM) and Cubic Kilometers per Second (km³/s) is:
It means that one cubic foot of air moving per minute is equal to a very tiny fraction of a cubic kilometer moving per second.
Example
For example you’re studying wind currents in the upper atmosphere. These airflows move at around 10 million CFM. To see how much air that is on a global scale, you need to convert it into Cubic Kilometers per Second (km³/s) using the right formula.
So, an airflow of 10 million CFM is equal to 4.71947 micro-cubic kilometers per second.
Now, let’s say you need to estimate the airflow of the jet stream, which can move at around 50 million CFM.
This result show that the jet stream moves approximately 0.0000236 cubic kilometers of air per second—a useful measurement when modeling global weather changes.
