What is atmosphere technical (at)?

Atmosphere technical (at) is a non-SI pressure unit defined as one kilogram-force per square centimetre, equivalent to 98,066.5 pascals, commonly used in historical engineering contexts.

What does petapascal (PPa) measure?

Petapascal (PPa) is an SI-derived unit of pressure equal to 10¹⁵ pascals, used to represent extremely large pressures in high-energy physics and astrophysics.

Why convert atmosphere technical to petapascal?

Converting atmosphere technical to petapascal enables translation of legacy pressure data into extremely high-pressure scales needed for modern physics research and astrophysical modeling.
