How many inhgs are in 1 bar?

1 bar equals 29.52998016 inhgs, using the exact defined conversion factor rather than an estimate.

How do I convert bar to inhg?

Multiply the bar value by 29.52998016. The converter above does this instantly to whatever precision you set.

How do I convert inhg back to bar?

Use the reverse factor: 1 inhg equals 0.03386389 bars. You can also use the swap control in the converter above to flip the direction instantly.

inHg (inHg) is a unit of pressure.

Is the bar to inhg conversion exact?

Yes. A bar is defined as exactly 100,000 pascals, close to (but distinct from) one standard atmosphere (101,325 Pa). That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.

Q: What is a bar?

Bar (bar) measures pressure. A bar is defined as exactly 100,000 pascals, close to (but distinct from) one standard atmosphere (101,325 Pa). It is classified as a Non-SI metric unit accepted for use with SI.

About Converting Bars to inHgs

Bar and inHg both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Bar is most often used for tire pressure specifications outside the us.

Formula

inhgs = bars × 29.5299801647

This factor comes from each unit's defined relationship to the category's base unit: 1 bar equals 100000 base units, and 1 inhg equals 3386.389 base units, so dividing one by the other gives the direct bar-to-inhg factor of 29.5299801647.

Simple example

1 bar × 29.52998016 = 29.52998016 inHg

1 bar = 29.52998016 inhgs.

Real-world example

35 bar × 29.52998016 = 1,033.549306 inHg

35 bars = 1,033.549306 inhgs.

Understanding the Bar

Bar (bar) measures pressure. A bar is defined as exactly 100,000 pascals, close to (but distinct from) one standard atmosphere (101,325 Pa). It is classified as a Non-SI metric unit accepted for use with SI.

Where it's used: Widely used in Europe and most of the world for tire pressure, weather, and industrial pressure

Uses of the Bar today

Tire pressure specifications outside the US
Meteorology (weather maps commonly use millibars, hPa)
Industrial and hydraulic pressure ratings in metric-system countries

History of the Bar

The bar was proposed by Norwegian meteorologist Vilhelm Bjerknes around 1906 as a convenient round pressure unit close to atmospheric pressure, derived from the CGS unit system (one bar equals one million dynes per square centimeter).

Though not an SI unit, the bar remains in wide practical use, particularly in meteorology (as the millibar, now more often written as the equivalent hectopascal) and in tire and hydraulic pressure specifications across most of the world.

Historical origin. Bar was not the invention of a single named person; it developed through the process described above.
