kPa to atm converter
1 kPa = 0.00986923 atm
And 1 atm = 101.325 kPa. Kilopascal to standard atmosphere.
Formula
atm = kPa × 0.00986923
A reading of 15 kPa is 15 × 0.00986923 = 0.148038 atm.

About these units
kPa (kilopascal): Common for HVAC, building ventilation and low-pressure gas work.
atm (standard atmosphere): Defined as 101,325 Pa, roughly sea-level air pressure.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
