Formula
Inches of Mercury = Kilopascal × 0.29529971
Worked Example
Example: 5 Kilopascal = 5 × 0.29529971 = 1.47649857 Inches of Mercury
To convert Kilopascal to Inches of Mercury, multiply the Kilopascal value by 0.29529971. This factor is derived from the ratio between the two units.
A kilopascal is a unit of pressure equal to 1,000 pascals. It is commonly used for tire pressure, blood pressure in some countries, and atmospheric pressure. Standard atmospheric pressure is approximately 101.325 kPa.
History
The kilopascal is a practical derivative of the pascal, the SI unit of pressure. It is widely used in Canada and Australia for tire pressure specifications. Weather services in many countries report atmospheric pressure in kilopascals or hectopascals.
Inches of mercury is a unit of pressure based on the height of a mercury column measured in inches. It is used in the United States for barometric pressure readings in weather reports and in aviation altimeter settings.
History
Inches of mercury is the traditional unit for barometric pressure in US weather forecasts. Standard atmospheric pressure is 29.92 inHg. Aviation uses inHg for altimeter settings in the US, while most other countries use hectopascals.
