CFM to in3/s [Cubic inches/sec] Calculator
🔄 CFM ↔ in³/s Converter
Contents
Conversion Formulas:
- 1 CFM = 28.8001 in³/s
- 1 in³/s = 0.034722 CFM
This conversion accounts for:
- 1 cubic foot = 1,728 cubic inches
- 1 minute = 60 seconds
- 1,728 ÷ 60 = 28.8001 in³/s per CFM
| CFM | in³/s |
|---|---|
| 0 | 0 |
| 1 | 28.8001 |
| 10 | 288.0012 |
| 100 | 2,880.0118 |
| 1000 | 28,800.1179 |
If you’re building a pneumatic system for an automated assembly line. The air compressor measures airflow in CFM (Cubic Feet per Minute), but the control valves need it in in³/s (Cubic Inches per Second). For smooth work, you need to convert between these two measurements.
How you do that manually? see following guide:
How to Convert CFM To in³/s
Remember that, 1 cubic foot contains 1,728 cubic inches, and there are 60 seconds in a minute, the conversion formula is:
Your air compressor operates at 5 CFM. Using the formula:
5 × 28.8001 = 144.0005
This means your air compressor delivers 144 cubic inches of air per second.
Result: Your control valve needs 150 in³/s of airflow for proper working. But your compressor only provides 144 in³/s, which is a little less than requirements. To keep the system running at its best, you might need a more powerful compressor.
