How many inHg in 1 nanopascal?
The answer is 2.9529983071445E-13.

We assume you are converting between **inch of mercury [0 °C]** and **nanopascal**.

You can view more details on each measurement unit:

inHg or
nanopascal

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

1 pascal is equal to 0.00029529983071445 inHg, or 1000000000 nanopascal.

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

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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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.

The SI prefix "nano" represents a factor of
10^{-9}, or in exponential notation, 1E-9.

So 1 nanopascal = 10^{-9} 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.
