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.

Frequently asked questions

How many kilopascals are in a atmosphere?

1 atmosphere = 101.325 kilopascals.

How do I convert atmospheres to kilopascals?

Use the formula kPa = atm × 101.325. For example, 5 atm = 506.625 kPa.

How do I convert kilopascals back to atmospheres?

1 kilopascal = 0.0098692327 atmospheres. Use the kPa to atm converter linked on this page.

Are these conversions exact?

Yes – all factors use the internationally defined values (for example 1 inch = 2.54 cm exactly, 1 pound = 0.45359237 kg exactly). Results are rounded to 8 significant digits for display.
