Question: 1 / 400

What is the standard barometric pressure at sea level?

520mmHg

635mmHg

760mmHg

The standard barometric pressure at sea level is universally recognized as 760 mmHg (millimeters of mercury). This value is established based on the average atmospheric pressure exerted by the weight of air above a given point at sea level.

The significance of this standard is crucial in various fields, especially in meteorology and aviation, as it helps to establish baseline measurements for atmospheric studies and can also affect the functioning of various medical devices that rely on pressure calibrations.

Other values like 520 mmHg, 635 mmHg, and 925 mmHg do not align with the scientifically established standard; thus, they are used in specific contexts or conditions but do not represent the baseline measurement for sea level pressure.
