When dealing with pressure measurements you may have to know the difference between kPa and atm, and how to convert between the two. Kilopascals (kPa) are units of one thousand pascals. Pascals are an international standard for pressure measurement, used for everything from bicycle tire pressure to meteorological change. The standard atmosphere unit (atm) is a fraction of the kilopascal and is gauged toward air pressure at sea level. Converting between kPa to atm can help in understanding pressure and pressure change.

1
Multiply the number of kPa by 1,000 to obtain the amount in pascals. For example, 10 kPa multiplied by 1,000 results in 10,000 pascals.

2
Divide the number of pascals by 101,325 to obtain the measurement in atm. For the example, 10,000 pascals divided by 101,325 equals .0986923266716 atm.
