What is a Standard atmosphere?

Standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa) and represents average atmospheric pressure at sea level.

What does picopascal measure?

Picopascal (pPa) is an SI-derived unit equal to 10⁻¹² pascals, used to quantify extremely small pressures common in vacuum and space research.

Why convert from atm to pPa?

Converting from atm to pPa enables measurement and expression of very low pressures in scientific experiments and high-precision instrument calibrations.
