Convert Pascal-seconds to Centipoise

Formula

cP = Pa·s × 1000

Derivation from SI units:

• 1 Pa·s = 1 N·s/m² = 1 kg·m⁻¹·s⁻¹
• 1 cP = 0.01 P = 10⁻³ Pa·s

Both units are defined exactly, so the factor is exact. Pascal-second definition: pascal-second; Centipoise definition: centipoise.

Worked examples

1. Whole blood at body temperature, about 0.0035 Pa·s, is 3.5 cP.
   0.0035 Pa·s × 1000 = 3.5 cP
2. Honey at about 2 Pa·s is 2000 cP.
   2 Pa·s × 1000 = 2000 cP

Where it's used

SI viscosities are converted to centipoise, the unit on most product datasheets and Brookfield readings. Multiply by 1000.
