Kilopascals to Standard Atmospheres Converter
1 kilopascal ≈ 0.00986923267 standard atmospheres
1 kilopascal equals 0.00986923 standard atmospheres
How to convert kilopascals to standard atmospheres
Unit conversion preserves the pressure reference. Gauge pressure and absolute pressure are different readings; changing between them also needs the ambient pressure. Mercury and water-column units use the conventions stated in their unit notes.
atm = kPa × 0.009869232667One kilopascal is 0.009869232667 standard atmospheres, so a single multiplication converts any value.
0.0986923 atm ≈ 10 × 0.009869232667Kilopascals to standard atmospheres conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
