**What is atmospheric pressure in metric?**

Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

### How do you calculate standard atmosphere?

The equations for pressure and density in the Standard Atmosphere are based on the Equation of State for Air (i.e., the Perfect Gas Law, p=ρRT) and the hydrostatic equation (equation 2.5). value of that quantity. a=sqrt(γRT)=sqrt(γp/ρ) where γ =1.4 for air.

**What is standard pressure in mmHg?**

760 mmHg

Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg). This is about 29.9 inches of mercury, and represents approximately 14.7 pounds per inch (14.7 lb/in2).

## What is standard pressure in kPa?

101.325 kPa

For example, standard atmospheric pressure (or 1 atm) is defined as 101.325 kPa. The millibar, a unit of air pressure often used in meteorology, is equal to 0.1 kPa. (For comparison, one pound per square inch equals 6.895 kPa.)

**What is standard atmospheric pressure in kPa?**

Normal atmospheric pressure at sea level is about 101,000 Pa; namely 101 kPa (kiloPascals).

**What is an atmosphere measurement?**

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

### What is STP in kPa?

Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 atm (101.325 kPa). Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar).

**Is kPa metric or imperial?**

The pascal (Pa) or kilopascal ( kPa ) as a unit of pressure measurement is widely used throughout the world, particularly in countries which follow the metric system. (most of Europe) and in some industries is largely replacing the pounds per square inch (psi) unit. 1 kPa is equal to 0.145038 PSI.

**How do I convert ISA temperature?**
