How to convert atmospheres to kilopascals
Formula: kPa = atm × 101.325
Worked example: 1 atm → 1 × 101.325 = 101.325 kPa

What is an atmosphere?
The standard atmosphere is defined as exactly 101,325 pascals, the average air pressure at sea level. Divers count roughly one extra atmosphere for every 10 meters, or 33 feet, of seawater.
What is a kilopascal?
The kilopascal equals 1,000 pascals. Canadian and many European car manuals give tire pressures in kPa, for example 240 kPa, which is about 35 psi. It is also used in engineering and for blood pressure in some medical texts.
