How to convert kilopascals to standard atmospheres
This changes units only. Gauge and absolute pressures need a known ambient pressure to relate them; the converter does not add atmospheric pressure.
Use x for the value in kPa, b for the intermediate value in Pa, and y for the result in atm.
atm = kPa × 1000 ÷ 101325
Worked examples
10 kPa ≈ 0.0986923266716 atm
Step 1: (10 × 1000) ≈ 10000 Pa.
Step 2: 10000 ÷ 101325 ≈ 0.0986923266716 atm.20 kPa ≈ 0.197384653343 atm
Step 1: (20 × 1000) ≈ 20000 Pa.
Step 2: 20000 ÷ 101325 ≈ 0.197384653343 atm.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilopascals
Kilopascals (kPa) measures pressure under the conventions above. The base value in Pa is (x × 1000), where x is the numerical value in kPa. Factors shown here are rounded for display; calculations use the stored factor.
About Standard atmospheres
Standard atmospheres (atm) measures pressure under the conventions above. The base value in Pa is (x × 101325), where x is the numerical value in atm. Factors shown here are rounded for display; calculations use the stored factor.
