What is the pressure, in kPa, of 420 mm Hg?Pressure:The pressure is described as the amount of external force applied to the object per unit of area. There are various units used in pressure measurement. Some of them are as follows: Pa, atm, mm of Hg, {eq}{\rm{N/}}{{\rm{m}...
What is the difference between kPa and kN/m^3? Measuring Pressure: Measurements of pressure are essentially measurements of a quantity of mass pressing against an area of a specific size. There are many units for measuring air pressure, with some of the earliest measurements of air pressure bei...
The kilopascal is a unit ofpressure. 1 kPa is approximately thepressureexerted by a 10-gmassresting on a 1-cm2area. 101.3 kPa = 1 atm. There are 1,000 pascals in 1 kilopascal. The pascal and thus the kilopascal are named for the French polymathBlaise Pascal. Kilopascal Uses The pasc...
The Kilopascal (kPa) is a unit of pressure measurement used in various scientific and engineering fields, including meteorology and aviation. It is part of the International System of Units (SI) and is defined as one thousand pascals.

Normal temperature and pressure (NTP) is one such standard reference for temperature and pressure. It is defined as air at the following conditions: Temperature: 20 degrees Celsius (293.15 degrees Kelvin, 68 degrees Fahrenheit) Pressure: 1 atm (101.325 kilonewton persquare meter, 101.325 kPa, 14....
1 kPa = 1,000 N ÷ 1 m2 A pascal is 1 newton of force applied at a right angle to 1 square meter. As can be seen in the above formulas, pressure and surface area are the inverse of each other. This means objects with a smaller surface area, such as a pin or drill bit, can...
