millimeter of mercury to hectopascal
Please provide values below to convert millimeter of mercury [mmHg] to hectopascal [hPa], or change ↔.
millimeter of mercury [mmHg]
Definition: The millimeter of mercury (mmHg) is a unit of pressure based on the height of a column of mercury.
Historyandorigin: This unit originated in the 17th century, when mercury barometers were first used to measure atmospheric pressure.
CurrentUse: It is still widely used in medical and scientific applications, especially to measure blood pressure.
funfact: A normal blood pressure reading for a healthy adult is usually expressed in millimeters of mercury, such as 120/80 mmHg.
hectopascal [hPa]
Definition: The hectopascal (hPa) is a metric unit of pressure equal to 100 pascals.
Historyandorigin: Historically, hectopascals were used in meteorology for easier handling of pressure values, as the pascal is quite small.
CurrentUse: It is still commonly used in meteorology to measure atmospheric pressure, particularly in weather reports.
funfact: Hectopascals are equivalent to millibars (mb), which is another unit commonly used in weather forecasting.

How to Convert millimeter of mercury to hectopascal
1 millimeter of mercury [mmHg] = 1.33322 hectopascal [hPa]
1 hectopascal [hPa] = 0.7500637554 millimeter of mercury [mmHg]
we use cross multiplication method
millimeter of mercury [mmHg] → hectopascal [hPa]
1 → 1.33322
1.5 → ?( suppose x)
=>1.5*1.33322=1*x
by simplifying
x=1.99983
