🔬 kPa to mmHg Converter
Instantly convert pressure from Kilopascals (kPa) to Millimeters of Mercury (mmHg). 1 kPa is exactly 7.50062 mmHg. This conversion is essential for blood pressure monitoring, medical applications, and engineering calculations.
What Is kPa?
Kilopascal (kPa) is a unit of pressure in the International System of Units (SI). One kilopascal equals 1,000 pascals (Pa), where one pascal is defined as one newton per square meter. kPa is commonly used in:
- Medical applications — blood pressure measurement in many countries.
- Meteorology — atmospheric pressure readings.
- Engineering — hydraulic and pneumatic systems.
- Automotive — tire pressure in many regions.
What Is mmHg?
Millimeter of Mercury (mmHg) is a manometric unit of pressure based on a column of mercury. It is defined as the pressure exerted by a 1 mm high column of mercury at 0 °C under standard gravity. mmHg is traditionally used in:
- Blood pressure measurement — the most common unit worldwide.
- Meteorology — barometric pressure readings.
- Medicine — intraocular pressure, central venous pressure, and more.
- Scuba diving — pressure gauges.
How to Convert kPa to mmHg
The formula to convert kPa to mmHg is:
mmHg = kPa × 7.50062
or mmHg = kPa × 760 / 101.325
The conversion factor 7.50062 is derived from the standard atmospheric pressure definition: 1 atm = 101.325 kPa = 760 mmHg[reference:1].
For example, to convert 101.325 kPa (standard atmospheric pressure) to mmHg:
mmHg = 101.325 × 7.50062
mmHg = 760.00 mmHg
To convert a blood pressure reading of 16 kPa (systolic) to mmHg:
mmHg = 16 × 7.50062
mmHg = 120.01 mmHg
