How to convert atmospheres to kilopascals
Multiply the number of atmospheres by 101.325 to get kilopascals: kPa = atm × 101.325.
Example: 5 atm = 506.625 kPa.
The atmosphere (atm) and the kilopascal (kPa) are both units of pressure. Need the opposite direction? Use the kPa to atm converter.

Metric and imperial units
The metric system (SI) is used by almost every country and by science worldwide. Its units scale by powers of ten – 1 kilometer is 1,000 meters, 1 meter is 100 centimeters – which makes conversions inside the system easy. The imperial and US customary systems (inches, feet, pounds, gallons) are still used daily in the United States and partly in the UK.
Since 1959 the inch has been defined as exactly 2.54 centimeters and the pound as exactly 0.45359237 kilograms, so conversions between the two systems are exact. Note that a US gallon (3.785 L) and an imperial gallon (4.546 L) are different – choose the right one above.
This converter covers 10 categories and 66 units: length, weight, temperature, volume, area, speed, time, data, energy, pressure.
