SLPM to SCFH Formula

The following equation is used to calculate the cubic feet per hour from liters per minute.

SCFH = SLPM/28.317 * 60 

Formula source:  NIST Miscellaneous Publication 121 – Units of Weight & Measure

  • Where SCFH is the standard cubic feet per hour
  • SLPM is standard liters per minute

To calculate SCFH from SLPM, divide the liters per minute by 28.317 to get cubic feet per minute, then multiply by 60 to convert to cubic feet per hour.

* Rounded to 3 decimals. Based on SCFH = (SLPM ÷ 28.317) × 60. Equivalently: 1 L/min ≈ 2.1189 SCFH; 1 ft³ ≈ 28.317 L.

What is a SLPM to SCFH?

Definition:

SLPM stands for standard liters per minute and SCFH stands for standard cubic feet per hour. These both represent volumetric flow rates at standard temperature and pressure.

How to Calculate SLPM to SCFH?

Example Problem:

The following example outlines the steps and information needed to calculate SLPM to SCFH.

First, determine the liters per minute. In this case, the SLPM is found to be 500 L/min.

Next, the final and last step is to use the formula above to convert the units:

SCFH = SLPM/28.317 * 60

SCFH = 500/28.317 * 60

SCFH = 1059.434 ft^3/hr
