1. What is SCFM to LPM Conversion?

The conversion between Standard Cubic Feet per Minute (SCFM) and Liters per Minute (LPM) is essential for comparing flow rates between different measurement systems. SCFM is commonly used in the US, while LPM is more common in metric countries.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( LPM \) — Liters per minute
• \( SCFM \) — Standard cubic feet per minute
• \( 28.3168 \) — Conversion factor (liters per cubic foot)

Explanation: The conversion factor comes from the definition that 1 cubic foot equals exactly 28.3168 liters.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering applications, medical equipment calibration, industrial processes, and when working with international specifications.

4. Using the Calculator

Tips: Enter SCFM value (must be positive). The calculator will automatically compute the equivalent in LPM.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between SCFM and CFM?
A: SCFM is measured at standard conditions (temperature and pressure), while CFM is the actual flow rate which varies with conditions.

Q2: Is this conversion temperature dependent?
A: No, since SCFM is already standardized to reference conditions (usually 68°F and 14.7 psi).

Q3: How precise is this conversion?
A: The conversion factor is exact, so the calculation is mathematically precise.

Q4: When would I need this conversion?
A: Common applications include medical oxygen flow, compressed air systems, and HVAC specifications.

Q5: Can I convert LPM back to SCFM?
A: Yes, simply divide LPM by 28.3168 to get SCFM.
