About Converting Zeptopascals to Centipascals
Zeptopascal and Centipascal 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: Zeptopascal is 1e-21 pascal units, and centipascal is 0.01 pascal units.
Formula
centipascals = zeptopascals × 1e-19
This factor comes from each unit's defined relationship to the category's base unit: 1 zeptopascal equals 1e-21 base units, and 1 centipascal equals 0.01 base units, so dividing one by the other gives the direct zeptopascal-to-centipascal factor of 1e-19.
Simple example
1 zPa × 1e-19 = 1e-19 cPa
1 zeptopascal = 1e-19 centipascals.
Real-world example
35 zPa × 1e-19 = 3.5e-18 cPa
35 zeptopascals = 3.5e-18 centipascals.

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

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