Kilopascals (kPa) to Bar (bar) Conversion
Kilopascals
The kilopascal (kPa) is a unit of pressure equal to exactly 1,000 pascals and is one of the most practical pressure units for everyday engineering. Standard atmospheric pressure is approximately 101.3 kPa. Tyre pressure is commonly specified in kPa in metric countries: a typical car tyre is inflated to 220–250 kPa. Blood pressure in clinical settings is measured in mmHg, but some medical devices express it in kPa (normal systolic ≈ 16 kPa).
Bar
The bar is a unit of pressure equal to exactly 100,000 pascals (100 kPa), accepted for use with the SI by the BIPM. It is close to one standard atmosphere (1 atm = 1.01325 bar) making it convenient for many practical applications. The bar is widely used in meteorology (weather maps), industrial gas and fluid systems, and tyre inflation in continental Europe. A typical car tyre is inflated to 2.2–2.5 bar; scuba diving tanks are filled to 200–300 bar.
