How can you convert kPa -> mmHg ?

1Pa = 1 N/m² 1kPa = 1000N/m²

The pressure of 1 mmHg is related to the force given by the mass of Hg over an given area.

Mass Hg m = v * density Hg

v = area 1 m² * height 0,001 m = 10^-3 m³

density Hg = 13,595 kg/dm³ = 13595 kg/m³

Mass Hg m = 10^-3[m³] * 13595 [kg/m³] = 13,595 kg

The force F = m * a a=g= gravity= 9,81 m/s²Force F = 13,595[kg] * 9,81[m/s²] =133,3 [kgm/s²] = 133,3 N

Definition 1N = 1kgm/s²

The force F 133,3 N (1mm Hg ) over 1 m² give a pressure P = 133,3 N/m²

P = 0,1333kPa

The pressure given by 1mmHg = 0,1333kPa

the inverse give us the answer of the question

1kPa = 1mmHg * 1 / 0,1333 = 7,5 mmHg

To convert from kPa to mmHg (millimeters of Mercury), you can use the conversion factor 1 kPa = 7.50062 mmHg. Simply multiply the pressure in kilopascals by 7.50062 to get the equivalent pressure in millimeters of mercury.

kPa x 7.501 = mmHg

  • 101.3 kPa x 7.501 = about 759.8 mmHg
