Is HG the same as PSI?
Is HG the same as PSI?
It is used for barometric pressure in weather reports, refrigeration and aviation in the United States. In older literature, an “inch of mercury” is based on the height of a column of mercury at 60 °F (15.6 °C). In Imperial units: 1 inHg60 °F = 0.489 771 psi, or 2.041 771 inHg60 °F = 1 psi.
How many PSI is a pound?
It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa….

How do you convert lbs to PSI?
Divide the number of pounds per square foot by 144. The quotient is the pounds per square inch. For example, 2,160 pounds per square foot converts to 15 pounds per square inch (2160 psf ÷ 144 = 15 psi).
Is mmHg same as Torr?
One unit of gas pressure is the millimeter of mercury (mmHg). An equivalent unit to the mmHg is called the torr, in honor of the inventor of the barometer, Evangelista Torricelli. Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa.

How much PSI is a lot?
Since you mentioned pressure washers, I’ll throw in a few other observations. Many electric models will do no more than 2000 PSI. Some gas-engine models can exceed 4,000 PSI. Pressures as low as 1000 PSI can still cause damage or personal injury, so be careful.
How to convert psi to in HG unit?
You can do the reverse unit conversion from in Hg to psi, or enter any two units below: The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units.
How to convert pressure to pounds per square inch?
