Conversion Formula
The formula to convert kilopascals to atmospheres is: atm = kpa * 0.00987. It works because the conversion factor 0.00987 represents the number of atmospheres in one kilopascal. For example, 45.2 kpa multiplied by 0.00987 equals about 0.446 atmospheres, showing the pressure in atmospheric units.
Conversion Example
- Convert 60 kpa to atm:
- – Multiply 60 by 0.00987, which gives 0.5922 atm.
- – Step 1: Write down 60 kpa.
- – Step 2: Use the conversion factor 0.00987.
- – Step 3: Multiply 60 * 0.00987 = 0.5922 atm.
- – Result: 60 kpa equals approximately 0.5922 atmospheres.

Conversion Definitions
kpa
KiloPascal (kpa) is a metric unit of pressure equal to 1,000 pascals, used to measure force per unit area in various scientific and engineering applications.
atmospheres
Atmospheres (atm) is a pressure unit based on Earth’s average sea-level atmospheric pressure, roughly 101.3 kilopascals, used to describe pressures in gases and liquids in scientific contexts.
Conversion FAQs
How accurate is the conversion factor 0.00987 for kpa to atm?
The factor 0.00987 is derived from the precise relationship where 1 atm equals 101.325 kpa, making the conversion quite accurate for most practical purposes. Minor variations may occur depending on calibration standards used.
Can I use this conversion for very high pressures?
While the formula works well for typical pressures, extremely high pressures might require more complex calculations taking into account temperature and other factors, as the simple conversion assumes standard conditions.
How do I convert atmospheres back to kpa?
To reverse the conversion, multiply atmospheres by 101.3. For example, 1 atm equals 101.3 kpa, so 0.5 atm equals 50.65 kpa.
Is the conversion affected by altitude or temperature?
The conversion factor itself remains the same regardless of altitude or temperature because it measures pressure units. However, actual pressure readings can vary due to environmental conditions.
What other units can kpa be converted into?
Kpa can be converted into psi (pounds per square inch), bar, or Torr, each requiring their specific conversion factors depending on the unit used.
