📏 What is an Atmosphere (atm)?

The atmosphere (atm) is a unit of pressure originally defined as the pressure exerted by the Earth’s atmosphere at sea level.

✅ Quick Facts:

1 atm = 101,325 Pascals (Pa)
Standard pressure in many scientific contexts
Widely used in chemistry, physics, meteorology, and engineering

🕰️ History & Significance:

The unit was historically established to represent the average atmospheric pressure at sea level on Earth. It’s a convenient reference point in gas laws (like Boyle’s or Charles’s Law) and in calibrating pressure instruments.

⚙️ Common Uses:

Chemistry lab measurements
Industrial process calibration
Diving equipment pressure
HVAC and mechanical systems
