Dynamic Viscosity Converter — Pa·s, Poise & Centipoise

Convert between pascal-seconds, poise, centipoise, and pound-based viscosity units using NIST factors.

—
How this conversion works. Every unit is converted through the pascal-second (SI) with factors from NIST Special Publication 811.

How to use

  1. Choose the units to convert from and to.
  2. Enter a value — the converted result updates instantly.

Frequently asked questions

How do I convert centipoise to pascal-second?

1 centipoise = 0.001 pascal-second. Choose "Centipoise (cP)" as From and "Pascal-second (Pa·s)" as To, type a value, and the result updates instantly.

Why is centipoise so common?

Water at 20 °C has a viscosity of almost exactly 1 cP (1.002 mPa·s), which makes cP an intuitive scale: olive oil ≈ 80 cP, honey ≈ 10,000 cP.

Is mPa·s the same as cP?

Yes, exactly: 1 cP = 1 mPa·s = 0.001 Pa·s. Datasheets use them interchangeably; SI style prefers mPa·s.

Is my data sent to a server?

No. Conversions run entirely in your browser using fixed factors — nothing is uploaded or logged.
