About Converting Centipascals to Zeptopascals
Centipascal and Zeptopascal both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Centipascal is 0.01 pascal units, and zeptopascal is 1e-21 pascal units.
Formula
zeptopascals = centipascals × 1e+19
This factor comes from each unit's defined relationship to the category's base unit: 1 centipascal equals 0.01 base units, and 1 zeptopascal equals 1e-21 base units, so dividing one by the other gives the direct centipascal-to-zeptopascal factor of 1e+19.
Simple example
1 cPa × 1e+19 = 1e+19 zPa
1 centipascal = 1e+19 zeptopascals.
Real-world example
35 cPa × 1e+19 = 3.5e+20 zPa
35 centipascals = 3.5e+20 zeptopascals.

Reverse conversion: Zeptopascal to Centipascal
1e+19 zPa × 1e-19 = 1 cPa
1e+19 zeptopascals = 1 centipascals.
centipascals = zeptopascals × 1e-19

Frequently asked questions
How many zeptopascals are in 1 centipascal?
1 centipascal equals 1e+19 zeptopascals, using the exact defined conversion factor rather than an estimate.
How do I convert centipascal to zeptopascal?
Multiply the centipascal value by 1e+19. The converter above does this instantly to whatever precision you set.
How do I convert zeptopascal back to centipascal?
Use the reverse factor: 1 zeptopascal equals 1e-19 centipascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a centipascal?
Centipascal (cPa) is a unit of pressure.
What is a zeptopascal?
Zeptopascal (zPa) is a unit of pressure.
Is the centipascal to zeptopascal conversion exact?
Yes. Both centipascal and zeptopascal are defined by fixed standards rather than physical artifacts, so the factor of 1e+19 used above is exact to as many digits as you choose to display.
