Standard atmospheric pressure is about 1.013 bar. A scuba tank is typically filled to 200 bar. In millimeters of mercury, that gives you: 1 bar = 750.062 mmHg, 10 bar = 7500.62 mmHg, 100 bar = 75006.2 mmHg.
The bar equals exactly 100,000 pascals — close to but not equal to standard atmospheric pressure (1 atm = 1.01325 bar). It is the working unit for compressed-air systems, pneumatic tools, dive computers, and weather pressure outside North America.
The millimeter of mercury (mmHg) equals approximately 133.322 Pa — the pressure exerted by a 1 mm column of mercury under standard gravity. It is the conventional unit for blood pressure worldwide, even in countries that have otherwise gone fully metric.
