The question is: How many atm are contained in 1520 mmHg of air pressure? The answer to that question depends on the system used to measure air pressure. The metric system uses the mmHg, which stands for millimeters of mercury. The mmHg, a manometric unit for pressure, is used often in blood pressure readings or meteorological reports. The Standard atmosphere (atm), which is 101,325 Pa or 776 mmHg, is the average atmospheric pressure at sea-level.
SI units use atmospheres to represent pressure and millimeters for pressure. One atmosphere equals 760.0 millimeters of mercury. Therefore, to convert a unit from one atmosphere to the other, you need to know how many atm are in fifteen20 mmHg. You can also use a calculator, pen and paper, or a pen and note. You must decide which unit you want to convert and what method you want to use.
