How do you change mm Hg into kpa?

Answer 1

1 kilopascal is about 7.5 mmHg

For example:

Say you have 360 mmHg and you want to convert it to kPa.

Using unit analysis. (360 mmHg) × (1 kPa) ÷ (7.5 mmHg) = 48 kPa

Answer 2

kPa = mm Hg * 133.32/1000

Note: You can't convert mm (unit of measurement) to kPa (unit of pressure)

this sort of sloppy maths could have contributed to the spherical shape of the Hubble mirror instead of a parabolic shape.

It is possible to convert between mm of Mercury or mm of paraffin, whatever substance used to measure pressure, and kPa. Take your mm measurement of the liquid and multiply it by the relative density of the liquid compared to water. Mercury density is 13.6 and paraffin is 0.85. Finally multiply it by gravity.

You should use the equation: Rho x Gravity x Height (in mm) of liquid measuring pressure.

Say you have 106 mm of mercury. This would equate to: 106 x 9.81 x 13.6 = 14142.096 pa or 14.142096 kPa. Check it with a calculator online somewhere

Answer 3

You can not convert it because they are different quantities.

However they are related to each other by definition:

Pressure = force / surface areaIn Standard Units:

Pascal = Newton / squared metre, or [Pa] = [N/m2]

Answer 4

Formula: mmHg x 0.1333 = kPa

Answer 5

To convert kPa to Pa, simply times the number with 1000. This is because 1kPa is equals to 1000 Pa. So for example, to convert 0.1kPa to Pa, just times 0.1 with 1000, which will give 100 Pa.

Answer 6

pa = 6894.75729 * psi

Answer 7

kPa x 0.145 = psi

Answer 8

1kPa is approx 101.9kg/m2
