You can do the reverse unit conversion from inch mercury to gigapascal, or enter any two units below:
gigapascal to kilopond/square millimeter
gigapascal to millitorr
gigapascal to kilogram-force/square millimeter
gigapascal to microbar
gigapascal to decipascal
gigapascal to centimeter of mercury
gigapascal to inch water
gigapascal to micrometer of mercury
gigapascal to decitorr
gigapascal to newton/square meter
The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.
So 1 gigapascal = 109 pascals.
The definition of a pascal is as follows:
The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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.
