Formula
atm = dyn/cm² × 9.869233e-7
Multiply any value in dynes per square centimetre by 9.869233e-7 to obtain the value in standard atmospheres.
Worked example
Convert 1.00000e+6 dyn/cm² to atm.
- 01Start with 1.00000e+6 dyn/cm².
- 02Multiply by the conversion factor: 1.00000e+6 × 9.869233e-7 = 0.986923 atm.
Result1.00000e+6 dyn/cm² = 0.986923 atm

FAQ
What is the conversion factor from dyn/cm² to atm?
1 dyn/cm² equals 9.869233e-7 atm. To convert, multiply the value in dynes per square centimetre by 9.869233e-7.
How do I convert 1 dyn/cm² to atm?
1 dyn/cm² = 9.86923e-7 atm. For any value, multiply by 9.869233e-7.
How do I convert atm back to dyn/cm²?
Divide by the same factor — or equivalently, multiply by 1013250. So 1 atm = 1.01325e+6 dyn/cm².
When would I need to convert dyne per square centimetre to standard atmosphere?
Pressure conversions between dyn/cm² and atm are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
