Pressure Converter

Convert a pressure value between pascal, kilopascal, bar, standard atmosphere, psi, and mmHg, with every unit shown in one table.

About Pressure Converter

Unit conversion re-expresses a measurement in another unit of the same quantity. Each unit here has a fixed factor to a base unit (metre, kilogram, square metre, litre, second, byte, pascal, joule), and the result is value × source factor ÷ target factor. Temperature uses formulas instead: °F = °C × 9 ÷ 5 + 32 and K = °C + 273.15. A month is taken as 30 days, a year as 365 days, and a cup as 240 ml.

How to use Pressure Converter

  1. Fill in "Quantity", "Value" and "Source unit".
  2. The result appears below and updates as you type.
  3. Copy the result with the copy button, or download it as a file where that is offered.

Questions about Pressure Converter

How do I choose the unit I am converting from?

Type the unit name or the start of it in the source unit box, such as km, mile, or lb. If the box is empty, the base unit of the quantity is used. For temperature, type f, k, or r; the default is Celsius.
