1. What is SCFH to LPM Conversion?

The SCFH (Standard Cubic Feet per Hour) to LPM (Liters Per Minute) conversion is used to convert between two common units of volumetric flow rate measurement, particularly in gas flow applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( SCFH \) — Standard cubic feet per hour
• \( 2.11888 \) — Conversion factor (1 ft³ = 28.3168 liters, 1 hour = 60 minutes)

Explanation: The conversion factor accounts for both volume unit conversion (cubic feet to liters) and time unit conversion (hours to minutes).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential in many industrial applications, including gas flow measurement, process control, and equipment specification where different units may be required.

4. Using the Calculator

Tips: Enter the SCFH value in the input field. The value must be a positive number. The calculator will automatically compute the equivalent LPM value.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between SCFH and LPM?
A: SCFH measures flow in cubic feet per hour at standard conditions, while LPM measures flow in liters per minute.

Q2: Why is the conversion factor 2.11888?
A: It combines the volume conversion (1 ft³ = 28.3168 liters) and time conversion (1 hour = 60 minutes): 28.3168/60 ≈ 0.471947, and 1/0.471947 ≈ 2.11888.

Q3: Are there different standard conditions?
A: Yes, standard conditions can vary (e.g., 0°C or 20°C, 1 atm or 14.696 psia). This calculator uses the most common definition (20°C, 1 atm).

Q4: Can this be used for liquid flow?
A: While the units are compatible, this conversion is typically used for gas flow. Liquid flow conversions would typically use different considerations.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined standard conditions. Accuracy in practice depends on measurement accuracy of the original SCFH value.
