Kilopascals (kPa) to Standard Atmospheres (atm) Converter
Convert Kilopascals (kPa) to Standard Atmospheres (atm) with high scientific precision. Essential for meteorology, chemical engineering, and diving applications.
About
Standard Atmosphere (atm) is a reference unit of pressure equal to the average air pressure at sea level at a latitude of 45 degrees. While the SI unit Pascal (and its multiple, Kilopascal) is preferred in modern physics, atm remains dominant in diving, aviation, and chemical thermodynamics to describe equations of state.
Accuracy in this conversion is non-negotiable for safety-critical computations such as diving decompression tables or chemical reaction vessel stress. This tool converts Kilopascals (kPa) to Standard Atmospheres (atm) using the exact defined relationship, maintaining sufficient decimal precision for scientific work.
Formulas
The standard atmosphere is exactly defined in relation to the Pascal. The conversion logic follows:
Where:
- 101.325 is the standard atmospheric pressure in kPa.
- 0 kPa represents a perfect vacuum.
