100 mmHg to Kilopascals

13.3322 kPa

100 mmHg = 13.3322 kPa

100 mmHg = 13.3322 kPa

To convert mmHg to kilopascals, multiply the value by the conversion factor:

1 mmHg = 0.133322 kPa
100 mmHg × 0.133322 = 13.3322 kPa

Reverse: 13.3322 kilopascals = 100 mmHg

mmHg (mmHg) kilopascals (kPa)
100 13.3322
80 10.6658
120 15.9986
140 18.6651
160 21.3315

mmHg (mmHg)

This unit literally measures pressure by how many millimeters it can push a column of liquid mercury up a tube. It dates back to the first barometers in the 1600s. Despite being archaic, it is the absolute global standard for measuring blood pressure. When a doctor says '120 over 80', they mean mmHg.

Normal systolic blood pressure is around 120 mmHg.

Commonly used in: Blood pressure, Meteorology, Vacuum pumps, Laboratory physics, Medicine.

kilopascals (kPa)

The kilopascal (kPa) is the practical metric unit for everyday pressure. It is widely used in countries that have fully adopted the metric system for tire pressure and engineering data. 100 kPa is conveniently close to 1 atmosphere of pressure.

Standard atmospheric pressure is about 101.3 kPa.

Commonly used in: Tire pressure (Metric countries), Building engineering, Scuba tank pressure, Meteorology, Medical ventilators.
