How many PSI is an inch of water column?
How many PSI is an inch of water column?
approximately 1/28 pound per square inch
One inch of water column is equal to a pressure of approximately 1/28 pound per square inch (psi). Stating this another way, a column water 28-inches high produces pressure that is equal to 1 psi.
How do you convert psig to psia?
The formulas to describe the relationship are: PSIG + 1 atm = PSIA and PSIA – 1 atm = PSIG (where atm is atmospheric pressure). It is easy to calculate PSIA or PSIG or convert between the two.
What’s the difference between PSI and psig?
PSI: This term is short for “pound-force per square inch,” typically referring to gas or liquid. PSIG: This is the term used for PSI in relation to atmospheric pressure. PSIG is also known as Gauge Pressure. The ambient pressure at sea level is about 14.7 PSIA, but ambient PSIG is always 0.
Is ATM a pressure?
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
How do you measure inches of water column?
How Do you Measure Water Column Gas Pressure?
- Turn the gas off.
- Locate the pressure tap on the gas valve and unscrew the plug.
- Turn the gas back on.
- Turn on the furnace and start it.
- The manometer will give the reading in Water Column in inches.
- Turn gas off.

What is the SI unit of pressure in inches?
The SI derived unit for pressure is the pascal. 1 pascal is equal to 0.00014503773800722 psig, or 0.0040146307866177 inch of water column. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between pounds/square inch and inches water column.
What is 1 psi equivalent to in Hg?
1 PSI is equivalent to 51.7149 Torr, 2.03602 inHg, 0.0689476 Bar, 0.068046 atmospheres, 27.7076 inches of water column, and so on. PSIG and PSIA are the two variations of PSI that are often used. PSI can be changed to various numbers of units that are used to measure pressure.
