Solving the equation for the pressure gives = where m are meter and hPa refers to hecto-Pascal. This may be interpreted as the lowest terms of the Taylor expansion of p = 1013.25 exp ( − h 8431 m ) hPa {\displaystyle p=1013.25\exp \left({\frac {-h}{8431{\text{ m}}}}\right){\text{ hPa}}} where exp is the exponential function .
In these equations, g 0, M and R * are each single-valued constants, while P, L, T, and h are multivalued constants in accordance with the table below. The values used for M, g 0, and R * are in accordance with the U.S. Standard Atmosphere, 1976, and the value for R * in particular does not agree with standard values for this constant. [2]
{{convert|123|cuyd|m3+board feet}} → 123 cubic yards (94 m 3; 40,000 board feet) The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked.
Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres. Flight levels are usually designated in writing as FLxxx, where xxx is a two- or three-digit number indicating the pressure altitude in units of 100 feet (30 m). In radio communications, FL290 ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems. In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1]

The meter is "read" as a differential pressure head in centimeters or inches of water. The venturi meter and manometer is a common type of flow meter which can be used in many fluid applications to convert differential pressure heads into volumetric flow rate, linear fluid speed, or mass flow rate using Bernoulli's principle.
