What is a hectopascal?

The hectopascal equals 100 pascals and is identical to the millibar. Weather maps and forecasts outside the US give air pressure in hectopascals; standard sea-level pressure is 1013.25 hPa, and a strong hurricane can drop below 950 hPa.

What is a millimeter of mercury?

The millimeter of mercury, about 133.32 pascals, comes from mercury barometers. It remains the unit of blood pressure worldwide: a reading of 120/80 mmHg means a systolic pressure of 120 and a diastolic pressure of 80.

Frequently asked questions

How many millimeters of mercury are in a hectopascal?
