Pascals to Millimeters of Mercury (mmHg) Converter: Usage, Formulas, and Note on the Origin of the Measurement Unit


The Pascals to Millimeters of Mercury (mmHg) converter is a useful tool for performing pressure conversions between these commonly used measurement units. In this article, we will explore how to use the converter, the mathematical formulas employed for conversions, and delve into the origin of the mmHg measurement unit.

How the Pascals to mmHg Converter Works:

The Pascals to mmHg converter utilizes simple mathematical formulas to perform conversions between these two pressure measurement units. Here are the conversion formulas used:

Conversion from Pascals to mmHg: mmHg = Pascals * 0.00750062

Conversion from mmHg to Pascals: Pascals = mmHg / 0.00750062

Using the Pascals to mmHg Converter:

The Pascals to mmHg converter is easy to use. Follow these steps to perform a conversion:

Step 1: Enter the number of Pascals you want to convert in the provided field.

Step 2: The converter will automatically perform the calculation and display the result in mmHg just below the Pascals input field.

Step 3: If you wish to perform a conversion from mmHg to Pascals, enter the number of mmHg in the dedicated second input field.

Step 4: The result in Pascals will be displayed automatically below the mmHg input field.

Example: Convert 1000 Pascals to mmHg and 760 mmHg to Pascals.


1000 Pascals * 0.00750062 = 7.50062 mmHg (rounded to five decimal places)

760 mmHg / 0.00750062 = 101333.59 Pascals (rounded to two decimal places)


1000 Pascals are approximately equal to 7.50 mmHg (rounded to two decimal places).

760 mmHg are approximately equal to 101333.59 Pascals.

Note on the Origin of the mmHg Measurement Unit:

The mmHg (millimeters of mercury) measurement unit is used to measure pressure in systems based on the height of mercury in a U-tube. This unit traces its origin back to the experiment of Italian physicist Evangelista Torricelli, who invented the mercury barometer in 1643. In this device, the height of the mercury column in a U-tube is used to measure atmospheric pressure.

The mmHg unit is widely used in medicine, meteorology, and physics, particularly for applications related to atmospheric pressure and pressure measurement in fluids.


The Pascals to Millimeters of Mercury (mmHg) converter is a practical tool for pressure conversions between these two measurement units. With the use of simple conversion formulas, you can easily perform conversions for various applications. The mmHg unit, with its historical origin tied to the invention of the mercury barometer, remains a crucial measurement unit in various scientific and medical fields for pressure measurement.
