In various scientific and industrial applications, pressure is measured using different units, such as bars and millimeters of mercury (mmHg). The bar is commonly used in engineering and meteorology, while millimeters of mercury is often used in medicine, particularly for blood pressure measurements, and in vacuum measurements.
In this article, we’ll explain the difference between bars and millimeters of mercury, provide the conversion formula, and guide you through using a Bars to Millimeters of Mercury (mmHg) Converter for accurate pressure conversions.
Understanding Bars and Millimeters of Mercury
- Bars: A bar is a metric unit of pressure defined as 100,000 pascals (Pa). It is approximately equal to the atmospheric pressure at sea level. One bar is slightly less than the average atmospheric pressure at sea level, which is around 1.013 bars.
- Millimeters of Mercury (mmHg): Millimeters of mercury is a unit of pressure based on the height of a column of mercury in a barometer. It is commonly used to measure blood pressure and in other applications involving vacuum or atmospheric pressure. Standard atmospheric pressure is approximately 760 mmHg at sea level.
Conversion Formula: Bars to Millimeters of Mercury (mmHg)
To convert between bars and millimeters of mercury, you need the conversion factor:
1 Bar = 750.062 Millimeters of Mercury (mmHg)
To convert bars to mmHg, multiply the number of bars by 750.062.
Conversion Formula:
Millimeters of Mercury (mmHg) = Bars × 750.062
Conversion Examples
Example 1: Converting 1 Bar to Millimeters of Mercury
Let’s say you have 1 bar and want to convert it to millimeters of mercury.
Millimeters of Mercury = 1 bar × 750.062 = 750.062 mmHg
So, 1 bar is equal to 750.062 mmHg.
Example 2: Converting 0.5 Bars to Millimeters of Mercury
Now, let’s convert 0.5 bars to millimeters of mercury.
Millimeters of Mercury = 0.5 bars × 750.062 = 375.031 mmHg
So, 0.5 bars is equal to 375.031 mmHg.
How to Use the Bars to Millimeters of Mercury Converter
A Bars to Millimeters of Mercury Converter is a simple tool that will allow you to quickly convert between bars and mmHg. Here’s how you can use the converter:
- Input the Number of Bars: Enter the pressure in bars that you wish to convert to millimeters of mercury.
- Get the Result: The tool will automatically calculate and display the equivalent pressure in mmHg based on the conversion factor.
By using the converter, you can save time and avoid manual calculation errors, especially when working with pressures in different units across various industries.
Common Uses for Bars to Millimeters of Mercury Conversion
Pressure measurements in bars and mmHg are used in a variety of industries and fields:
- Blood Pressure Measurement: The most common application of mmHg is in medical settings, where blood pressure is measured in millimeters of mercury (e.g., 120/80 mmHg). However, when dealing with more technical aspects of blood pressure or atmospheric pressure, you may need to convert these values to bars for standardization.
- Atmospheric Pressure: Both bars and millimeters of mercury are used to express atmospheric pressure. Standard atmospheric pressure at sea level is defined as 1 bar or 760 mmHg.
- Vacuum and Pressure Systems: In the industrial sector, vacuum and pressure systems are often monitored and calibrated using bars and mmHg. Accurate pressure conversions are crucial in maintaining the correct pressure in systems like pumps, valves, and tanks.
- Meteorology: Meteorologists use pressure measurements in bars to study weather patterns and atmospheric conditions. Millimeters of mercury are also used in weather stations to report local air pressure.

Frequently Asked Questions (FAQs)
Q: What is the difference between bars and millimeters of mercury?
A: Bars are a metric unit of pressure that are based on the pascal (Pa), while millimeters of mercury (mmHg) measures pressure by the height of a mercury column in a barometer. One bar is approximately equal to 750 mmHg.
Q: Why is pressure sometimes measured in mmHg?
A: Millimeters of mercury are used in fields like medicine and physics because of the historical use of mercury barometers. For instance, blood pressure is commonly measured in mmHg because it provides a consistent and easy-to-read scale.
Q: How do I convert from mmHg back to bars?
A: To convert millimeters of mercury to bars, use the reverse conversion:
Bars = Millimeters of Mercury (mmHg) ÷ 750.062
For example, to convert 1,500 mmHg to bars:
Bars = 1,500 ÷ 750.062 = 2 bars
Q: Are there any other units of pressure I should know about?
A: Yes, there are several other units of pressure, such as atmospheres (atm), pascals (Pa), and pounds per square inch (psi). Each is used in different fields depending on the context of pressure measurements.
