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 mmHg to kPa, multiply by 0.133322. So, 345 mmHg is equivalent to 45.99 kPa.
11.1 kPa is 83.26mm Hg
A pressure of 340 mmHg is equal to 45.3 kPa (kilopascals). To convert mmHg to kPa, you can use the conversion factor 1 mmHg = 0.133 kPa.
The correct pressure in kPa would be 104.4 kPa. To convert mmHg to kPa, you can use the conversion factor: 1 mmHg = 0.133322 kPa. So, 783.0 mmHg * 0.133322 kPa/mmHg = 104.4 kPa.
To convert kPa to mmHg, you can use the conversion factor: 1 kPa = 7.5 mmHg. Simply multiply the pressure in kPa by 7.5 to get the equivalent in mmHg.
