Which unit is used internationally for pressure measurement?

Explanation:
Pascal is the international standard unit for pressure in the SI system. It is defined as one newton per square meter, which provides a universal way to express pressure across science and engineering disciplines worldwide. Using Pa (and its common multiples like kPa and MPa) lets everyone compare measurements without converting between regional unit systems. Other units such as atmosphere, bar, and Torr are still used in specific contexts or older specifications, but they are not the SI standard for international use. For perspective, 1 atmosphere is 101,325 Pa; 1 bar is 100,000 Pa; and 1 Torr is about 133.322 Pa. In practice, engineers and hazmat professionals often work with Pa or kPa to keep calculations and device readings consistent.
