The atmospheric pressure at sea level is 14.7 psi. Atmospheric pressure is also often stated as pounds/square inch (psi). Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa.
Another commonly used unit of pressure is the atmosphere (atm). A pascal is a very small amount of pressure, so the more useful unit for everyday gas pressures is the kilopascal (kPa).
The pascal (Pa) is the standard unit of pressure. An equivalent unit to the mmHg is called the torr, in honor of the inventor of the barometer, Evangelista Torricelli. One unit of gas pressure is the millimeter of mercury (mmHg). Tire pressure is best measured when the tire is cold since driving the car for a while will heat up the air in the tire and increase the pressure.Ī barometer measures gas pressure by the height of the column of mercury. The pressure on the tire is the maximum pressure for that tire, not the recommended one. 1.026315789 atm (standard atmosphere) 1.060417649 at (technical atmosphere) 780 torr 10604.178035561 mmH2O (mm of water) 780 mmHg (mm of mercury) 30.708653781 inHg (inches of mercury) 15.082700224 psi (pounds per sq.

The recommended pressure for that model of car (usually somewhere between 32-35 psi) is usually listed in the owner’s manual or stamped somewhere inside the door. The car gets better gas mileage and the tires don’t wear out as fast. The ride is smoother and safer than with lowered pressure.

The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.Ĭonversion calculator for all types of measurement units. P1 (initial pressure) 780 mmHg P2 (final pressure) 760 mmHg Solution: This problem can be solve using Boyles Law which state that volume is inversely proportional to pressure when the amount and temperature of gas are constant. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure.
