History

Atmosphere (atm)

The atmosphere, symbol atm, is a pressure unit originally based on average sea-level air pressure on Earth, defined as 101,325 pascals. First used in the 19th century for meteorology and engineering, the atmosphere is a convenient unit of measurement for expressing pressure in science, including chemistry, physics, and gas laws. Though largely replaced by SI units in formal texts, it remains widely recognized in academia and industry. Its historical role and practical magnitude sustain its relevance in global pressure measurements.

Kilopascal (kPa)

The kilopascal, symbolized as kPa, equals 1,000 pascals and is commonly used for practical pressure measurements in engineering, meteorology, and everyday life. It offers a more manageable scale than the single pascal, suitable for expressing atmospheric, tire, and fluid pressures. Using kilopascals maintains SI system compatibility, ensuring straightforward conversion to other metric or imperial units. Its use enhances clarity and accuracy in scientific papers, industry practices, and technical documents worldwide.
