Atmospheres to Kilopascals Conversion
Converting Atmospheres (atm) to Kilopascals (kPa) is a common pressure conversion. 1 atm equals 101.325 kPa. For example, 100 atm is equal to 10,132.5 kPa.
Quick Reference Values
1 atm = 101.325 kPa. 5 atm = 506.625 kPa. 10 atm = 1,013.25 kPa. 25 atm = 2,533.125 kPa. 50 atm = 5,066.25 kPa. 100 atm = 10,132.5 kPa.
What is Atmospheres?
Atmospheres (atm) is a unit of pressure. One atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa). It approximates the average air pressure at sea level on Earth. The atmosphere unit is used for expressing pressures in meteorology and engineering [iso-80000]. The atmosphere was originally defined in the 19th century based on average sea-level air pressure. It was standardized by the International Union of Pure and Applied Chemistry (IUPAC) and other bodies to equal 101,325 Pa in the mid-20th century [nist-sp-811]. Atmospheres are used worldwide in scientific fields, including chemistry and physics, and in engineering applications like pressure vessel design. It is less common in everyday use outside these fields [nist-sp-811].
What is Kilopascals?
Kilopascals (kPa) is a unit of pressure. A kilopascal equals 1,000 pascals, where 1 pascal is one newton per square meter. It is a unit of pressure used to quantify forces applied over an area and is part of the SI system [bipm-si-brochure]. Standard atmospheric pressure is approximately 101.325 kPa. The pascal was named in 1971 by the CGPM in honor of Blaise Pascal, a pioneer in fluid mechanics and pressure measurement. The kilopascal was adopted to express practical pressure values more conveniently [cgpm-resolutions]. Kilopascals are widely used in meteorology, engineering, and automotive industries worldwide. Countries using the SI system apply kPa for tire pressure, weather reports, and material stress testing [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: atmosphers, atmosfere, atmospere, atmospherics, kpa, kilo pascals, kilopascal. All of these refer to the Atmospheres to Kilopascals conversion.
