About atmospheres and mmHg
The Conversion Formula
To convert atmospheres to mmHg, multiply the value by the conversion factor: 1 atm = 760 mmHg. For a worked example, suppose you need to convert 25 atm to mmHg: 25 × 760 = 19000.05 mmHg. To convert in the opposite direction, divide by 760, or equivalently multiply by 0.00131579.
About atmospheres
The standard atmosphere (atm) represents the average pressure exerted by Earth's atmosphere at sea level. It was originally defined by the height of mercury in a barometer (760 mm). It is the most intuitive unit for understanding pressure: 2 atm means double the pressure you feel standing on the beach. atmospheres are commonly used in Diving depth (1 atm per 10m), Chemistry (Standard Temp/Pressure), Hyperbaric chambers, and Spacecraft engineering, Altitude simulation.
At sea level, the air pressure is exactly 1 atm.
About mmHg
This unit literally measures pressure by how many millimeters it can push a column of liquid mercury up a tube. It dates back to the first barometers in the 1600s. Despite being archaic, it is the absolute global standard for measuring blood pressure. When a doctor says '120 over 80', they mean mmHg. mmHg are commonly used in Blood pressure, Meteorology, Vacuum pumps, and Laboratory physics, Medicine.
Normal systolic blood pressure is around 120 mmHg.
When Would You Convert atmospheres to mmHg?
Converting between atmospheres and mmhg is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 atm = 760 mmHg) memorized or bookmarked can save time in professional and everyday contexts alike.
