How do you convert mm of mercury to ATM?
One millimeter of mercury is equal to 0.0013157896611399 atmospheres. This means that to convert mmHg to atm you should multiply your figure by 0.0013157896611399.
How do you convert ATM to MM?
1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi.
What is mercury’s ATM?
standard atmosphere, unit of pressure, equal to the mean atmospheric pressure at sea level. It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high.
Is mmHg and Torr the same?
A barometer measures gas pressure by the height of the column of mercury. 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. The pascal (Pa) is the standard unit of pressure.
How do you convert cm to atm pressure?
cmHg↔atm 1 atm = 76 cmHg.
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.
Can you use mercury card at ATM?
Yes, our debit cards can be used at ATMs. We don’t charge any fees on top of what the ATM operator charges. Our cards are part of the Allpoint ATM network, so Allpoint won’t charge any fees on cash withdrawals with Mercury debit cards.
What is the size of Mercury’s atmosphere?
The near-surface concentrations of these elements were estimated to vary from 230 cm−3 for hydrogen to 44,000 cm−3 for oxygen, with an intermediate concentration of helium.
How many mm of mercury in an atmosphere?
One atmosphere is equal to 29.9 inches (760 mm) of mercury, or 760 mm H; atmospheres are the units of pressure used in the international standard, or SI, system of measurement. Standard pressure is one atmosphere, or 760 millimeters of mercury, and is the base pressure used in many scientific calculations.
How many mm Hg per ATM?
1 atm is equal to 1 mmHg 14.7 mmHg 76 mmHg 760 mmHg. 1 atm is equal to 760 mmHg.
How many atmospheres in Mercury?
Mercury has a very tenuous and highly variable atmosphere (surface-bound exosphere) containing hydrogen, helium, oxygen, sodium, calcium, potassium and water vapor, with a combined pressure level of about 10 −14 bar (1 nPa). The exospheric species originate either from the Solar wind or from the planetary crust.
What is mm Mercury?
A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322 387 415 pascals. It is denoted mmHg or mm Hg. Although not an SI unit, the millimetre of mercury is still routinely used…
