About psi
PSI stands for 'Pounds per Square Inch'. It is the standard unit for pressure in the United States. It measures how many pounds of force are pressing on every square inch of surface. It is the unit every American driver looks for when filling their tires. psi are commonly used in Tire pressure (US), Blood pressure (rarely), Scuba tanks (US), and Industrial pumps, Paintball tanks.
A standard car tire is inflated to 30-35 psi.
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 psi to mmHg?
Converting between psi 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 psi = 51.7151 mmHg) memorized or bookmarked can save time in professional and everyday contexts alike.
