Converting Pressure: Atmospheres to Pascals
When measuring pressure, two of the most fundamental units are the standard atmosphere (atm) and the Pascal (Pa). The atmosphere is a historical unit based on the Earth's air pressure, while the Pascal is the standard unit of pressure in the International System of Units (SI). Understanding how to convert between them is essential in many scientific and engineering fields.
What is a Standard Atmosphere (atm)?
A standard atmosphere (atm) is a unit of pressure defined as the approximate average atmospheric pressure at sea level. It provides a convenient reference point that is easy to conceptualize.
What is a Pascal (Pa)?
The Pascal (Pa) is the SI derived unit of pressure. It is defined as one newton of force per square meter (1 N/m²). Because the Pascal is a very small unit, pressure is often expressed in kilopascals (kPa), where 1 kPa = 1,000 Pa, or megapascals (MPa), where 1 MPa = 1,000,000 Pa.
