How do you convert air pressure?
1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi. The prefix “kilo” means “1,000”, so one kilopascal = 1,000 Pa. Therefore, 101.325 kPa = 1 atm = 760 torr and 100 kPa = 1 bar = 750 torr. The prefix “mega” means “1,000,000”, so one megapascal = 1,000 kPa = 1,000,000 Pa = 9.869 atm = 145 psi.
How do you convert barometric pressure to air pressure?
One atmosphere of barometric pressure is equal to 760 millimeters of mercury. Get your barometric pressure reading in atmospheres. Multiply the barometric pressure reading in atmospheres by 760 millimeters of mercury.
How do you convert air pressure to inches?
To convert millibars to inches of mercury, multiply the millibar value by 0.0295301.
How much does air pressure change for every 1000 feet?
A standard pressure lapse rate is when pressure decreases at a rate of approximately 1 “Hg per 1,000 feet of altitude gain to 10,000 feet.
What is the value of 1 atm pressure?
101,325 pascals
One standard atmosphere, which is also referred to as one atmosphere, is equivalent to 101,325 pascals, or newtons of force per square metre (approximately 14.7 pounds per square inch).
What is meant by 1 torr of pressure?
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly 1760 of a standard atmosphere (101325 Pa). Thus one torr is exactly 101325760 pascals (≈ 133.32 Pa).
