Convert standard atmosphere to pascal
Standard Atmosphere
The standard atmosphere (symbol: atm) is a unit of pressure defined as exactly 101,325 pascals (101.325 kPa). It was originally defined as the average atmospheric pressure at sea level on Earth. The standard atmosphere is commonly used as a reference pressure in chemistry, physics, and aviation.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
