Atmospheres to Pascals: 1 atm equals 101325 Pa. To convert atmospheres to pascals, multiply by 101325 (Pa = atm × 101,325). For example, 10 atm = 1013250 Pa.
How to Convert Atmospheres to Pascals
To convert from atmospheres to pascals, multiply the value by 101325. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Atmospheres to Pascals:
Pa = atm × 101,325 - Pascals to Atmospheres:
atm = Pa ÷ 101,325

Understanding the Units
What is an Atmosphere?
A standard atmosphere equals exactly 101,325 pascals — defined as the average atmospheric pressure at sea level.
Common contexts: chemistry, reference conditions.
What is a Pascal?
The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).
Named after Blaise Pascal (1623–1662), the French mathematician and physicist whose experiments characterized atmospheric pressure.
Common contexts: fluid mechanics, meteorology.
