Atmospheres to Pascals Converter
Convert atmospheric pressure (atm) to pascals (Pa) and other pressure units. Accurate pressure conversion calculator for scientific, engineering, and weather applications.
Step 1: Pressure Input
Conversion Reference
1 standard atmosphere (atm) = 101,325 pascals (Pa) = 1.01325 bar = 14.6959 psi = 760 torr (mmHg). This is based on the International Standard Atmosphere.
Step 2: Settings & Options
Common Pressure References
Standard atmospheric pressure at sea level: 1 atm. Weather systems: 980-1040 hPa. Car tire pressure: ~30-35 psi. Blood pressure: ~120/80 mmHg.
Quick Conversions
Atm to Pa: Multiply by 101,325. Pa to Atm: Divide by 101,325. Bar to Atm: Multiply by 0.986923. Psi to Atm: Divide by 14.6959.

Conversion Formula & Information
Atmospheres to Pascals Formula
Pascals = Atmospheres × 101,325
Where 101,325 Pa is the standard atmospheric pressure at sea level at 15°C (59°F). This is defined by the International Standard Atmosphere (ISA).
