The SI derived unit for **pressure** is the pascal.

1 pascal is equal to 0.001 centibar, or 0.00029529983071445 inch of mercury.

Note that rounding errors may occur, so always check the results.

40 centibar to inch of mercury = 11.81199 inch of mercury

50 centibar to inch of mercury = 14.76499 inch of mercury

75 centibar to inch of mercury = 22.14749 inch of mercury

100 centibar to inch of mercury = 29.52998 inch of mercury

You can do the reverse unit conversion from inch of mercury to centibar, or enter any two units below:

centibar to centipascal

centibar to kip/square foot

centibar to femtopascal

centibar to kilopond/square millimeter

centibar to millipascal

centibar to inch mercury

centibar to gram/square centimeter

centibar to kilopond/square meter

centibar to millimeter water

centibar to gigapascal

The SI prefix "centi" represents a factor of
10^{-2}, or in exponential notation, 1E-2.

So 1 centibar = 10^{-2} bars.

The definition of a bar is as follows:

The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The word bar is of Greek origin, báros meaning weight. Its official symbol is "bar"; the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.

Inches of mercury or inHg is a non-SI unit for pressure. It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.

It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 °F (0 °C) at the standard acceleration of gravity.

1 inHg = 3,386.389 pascals at 0 °C.

Aircraft operating at higher altitudes (above 18,000 feet) set their barometric altimeters to a standard pressure of 29.92 inHg or 1,013.2 hPa (1 hPa = 1 mbar) regardless of the actual sea level pressure, with inches of mercury used in the U.S. and Canada. The resulting altimeter readings are known as flight levels.

Piston engine aircraft with constant-speed propellers also use inHg to measure manifold pressure, which is indicative of engine power produced.
