CMH to LPM Conversion Formula:
| From: | To: |
CMH to LPM conversion is the process of converting flow rate measurements from cubic meters per hour to liters per minute. This conversion is commonly used in engineering, HVAC systems, fluid dynamics, and industrial applications where flow rates need to be expressed in different units.
The conversion formula is based on unit relationships:
Where:
Explanation: Since 1 cubic meter equals 1000 liters and 1 hour equals 60 minutes, the conversion factor is derived from 1000 ÷ 60 = 16.666666666666668.
Details: Accurate flow rate conversion is essential for system design, equipment specification, process control, and ensuring compatibility between different measurement systems used in international projects and technical documentation.
Tips: Enter the flow rate in cubic meters per hour (CMH). The value must be non-negative. The converter will automatically calculate the equivalent flow rate in liters per minute (LPM).
Q1: Why is the conversion factor 16.6667?
A: The factor comes from 1000 liters per cubic meter divided by 60 minutes per hour: 1000 ÷ 60 = 16.6667.
Q2: When is this conversion typically used?
A: Commonly used in HVAC systems, water treatment plants, industrial processes, and any application where fluid flow rates need to be expressed in different standard units.
Q3: What's the difference between CMH and LPM?
A: CMH measures volume flow per hour, while LPM measures volume flow per minute. LPM provides a more granular view of flow rates for real-time monitoring.
Q4: Can I convert LPM back to CMH?
A: Yes, the reverse conversion is: CMH = LPM ÷ 16.6667 or CMH = LPM × 0.06.
Q5: Are there any limitations to this conversion?
A: This conversion assumes standard temperature and pressure conditions. For gases, actual flow rates may vary with temperature and pressure changes.
