About Bar (bar)
A metric unit of pressure equal to exactly 100,000 pascals (100 kPa), approximately equal to Earth's average sea-level atmospheric pressure. Not an SI unit but widely accepted for engineering use. Bars are the default unit in European industry for compressed gas, hydraulics, and process plants; car tire pressures in much of the world are quoted in bar (about 2.2 bar for a passenger car). Gauges on scuba equipment, brewery CO₂ tanks, and espresso machines typically read in bar.
About Millimeters of Mercury (mmHg)
A unit of pressure historically defined as the pressure exerted by a 1-millimeter column of mercury at standard gravity. Millimeters of mercury are the default unit for clinical blood-pressure readings worldwide ("120 over 80") and intraocular pressure in ophthalmology. The mmHg is numerically almost identical to the torr (1 mmHg ≈ 1.0000007 torr). Barometric atmospheric pressure was historically quoted in mmHg as well — 760 mmHg = 1 atm.

Understanding Bar
The Bar (symbol: bar) is a unit of pressure. A metric unit of pressure equal to exactly 100,000 pascals (100 kPa), approximately equal to Earth's average sea-level atmospheric pressure. Not an SI unit but widely accepted for engineering use. Bars are the default unit in European industry for compressed gas, hydraulics, and process plants; car tire pressures in much of the world are quoted in bar (about 2.2 bar for a passenger car). Gauges on scuba equipment, brewery CO₂ tanks, and espresso machines typically read in bar.
It belongs to the metric measurement system.

Millimeters of Mercury are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Why Convert Bar to Millimeters of Mercury?
Engineers, mechanics, and scientists frequently need to convert pressure between Bar and Millimeters of Mercury when working with different measurement standards. Tire pressure, blood pressure readings, weather barometric measurements, and industrial process specifications may all use different pressure units depending on the region or discipline. Reliable conversion prevents equipment misuse and ensures safety.
Frequently Asked Questions
How do I convert Bar to Millimeters of Mercury?
A metric unit of pressure equal to exactly 100,000 pascals (100 kPa), approximately equal to Earth's average sea-level atmospheric pressure. To convert Bar to Millimeters of Mercury, multiply by 750.064. For example, 25 bar equals 18751.6 mmHg.
How many Millimeters of Mercury are in 1 Bar?
There are 750.064 Millimeters of Mercury in 1 Bar.
How many Bar are in 1 Millimeters of Mercury?
There are 0.00133322 Bar in 1 Millimeters of Mercury.
What is the formula for Bar to Millimeters of Mercury conversion?
The formula is: multiply by 750.064. This means 1 bar = 750.064 mmHg.
Is a Bar bigger than a Millimeters of Mercury?
No. One Bar is smaller than one Millimeters of Mercury because 1 bar equals 750.064 mmHg, which is greater than 1.
When do you need to convert between Bar and Millimeters of Mercury?
A unit of pressure historically defined as the pressure exerted by a 1-millimeter column of mercury at standard gravity. Bar and Millimeters of Mercury are both pressure units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
