mm Hg or
kPa

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

1 pascal is equal to 0.0075006157584566 mm Hg, or 0.001 kPa.

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

1 mm Hg to kPa = 0.13332 kPa

5 mm Hg to kPa = 0.66661 kPa

10 mm Hg to kPa = 1.33322 kPa

20 mm Hg to kPa = 2.66645 kPa

30 mm Hg to kPa = 3.99967 kPa

40 mm Hg to kPa = 5.3329 kPa

50 mm Hg to kPa = 6.66612 kPa

75 mm Hg to kPa = 9.99918 kPa

100 mm Hg to kPa = 13.33224 kPa

You can do the reverse unit conversion from kPa to mm Hg, or enter any two units below:

The millimeter of mercury by definition is 133.322387415 Pa (13.5951 g/cm3 × 9.80665 m/s2 × 1 mm), which is approximated with known accuracies of density of mercury and standard gravity.

The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 pascals. Therefore, 1 Torr is equal to

101325/760 Pa. The decimal form of this fraction is approximately 133.322368421.

The relationship between the torr and the millimeter of mercury is:

1 Torr = 0.999999857533699 mmHg

1 mmHg = 1.000000142466321 Torr

The difference between one millimeter of mercury and one torr, as well as between one atmosphere (101.325 kPa) and 760 mmHg (101.3250144354 kPa), is less than one part in seven million (or less than 0.000015%). This small difference is negligible for most applications outside metrology.

The SI prefix "kilo" represents a factor of
10^{3}, or in exponential notation, 1E3.

So 1 kilopascal = 10^{3} 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.
