The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). [1][2] By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth ...
The unit, named after Blaise Pascal, is an SI coherent derived unitdefined as one newtonper square metre(N/m2).[1] It is also equivalent to 10 barye(10 Ba) in the CGSsystem. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar.
Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 10 5 Pa (100 kPa, 1 bar). NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). [ 3 ] This standard is also called normal temperature and pressure (abbreviated as NTP).
Orders of magnitude (pressure) This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. psi values, prefixed with + and -, denote values relative to Earth's sea level standard atmospheric pressure (psig); otherwise, psia is assumed. Magnitude. Pressure. lbf/in 2 or dB.
The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2] The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is ...
It is not a part of the International System of Units (SI), the modern metric system. 1 kgf/cm 2 equals 98.0665 kPa (kilopascals) or 0.980665 bar —2% less than a bar. It is also known as a technical atmosphere (symbol: at). [1][2] Use of the kilogram-force per square centimetre continues primarily due to older pressure measurement devices ...
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
Behaviorally anchored rating scales (BARS) are scales used to rate performance.BARS are normally presented vertically with scale points ranging from five to nine. It is an appraisal method that aims to combine the benefits of narratives, critical incidents, and quantified ratings by anchoring a quantified scale with specific narrative examples of good, moderate, and poor performance.
