Nitrogen Conversion Factors

SPECIAL NOTE: Many "other" manufacturers claim to provide you with a flow and purity that you require, but neglect to tell you that this flow will only occur at  70^oF at sea level (standard conditions). If you operate at higher elevations you will never reach your anticipated flow requirements. Let NiOxy design a system that will generate the flow that you require at your elevation!

All industrial gases are typically measured in the following units:

SCFH:   Standard Cubic Feet per Hour

SCFM:   Standard Cubic Feet per Minute

Nm³/hr: Normal Cubic meters per hour

Sm³/hr: Standard Cubic Meters per hour

The most common units of industrial gas measurement are; SCFH and Nm³/hr. Note, that there is a difference between Normal cubic meters and Standard cubic meters. The difference lies in the reference temperature that each specific unit is measured with respect to. Normal meters are measured with respect to the Metric system (0⁰C, 1 atm), and standard meters are measured with respect to the imperial system of standard conditions (70⁰F, 1atm).

 1 Normal Cubic Meter equals 37.43 SCF

N.B. There is a difference between a Normal Cubic Meter and a Standard Cubic Meter

Nitrogen:

1 U.S. Gallon     93.11 SCF

1 Pound            13.80 SCF

Gas Conversions
	The most common mistake done in converting standard cubic feet to cubic meters is using normal cubic meters and standard cubic meters interchangeably. They aren't equivalent units.
