How to Convert Centipoise to Millipascal-seconds

Formula

To convert Centipoise (cP) to Millipascal-seconds (mPa·s): multiply by 1

Step-by-Step

  1. Start with your value in Centipoise (cP).
  2. Multiply by 1 to perform the conversion.
  3. The result is your value expressed in Millipascal-seconds (mPa·s).

Conversion Factor

1 cP = 1 mPa·s

Reverse Factor

1 mPa·s = 1 cP

Worked Example

Convert 25 Centipoise to Millipascal-seconds: 25 cP = 25 mPa·s

About Centipoise (cP)

A CGS dynamic-viscosity unit equal to exactly 0.01 poise = 0.001 Pa·s = 1 mPa·s. Centipoise is the traditional working unit in coatings, paints, petroleum products, food processing, and pharmaceutical excipient characterization — Brookfield rotational viscometers (the industry-standard QC instrument since the 1930s) default to reporting in cP on the dial readout. Test methods: ASTM D445 (kinematic viscosity, but cross-references to cP via density), ASTM D2196 (rheological properties via rotational viscometer), ASTM D562 (Stormer viscometer Krebs Units, with cP cross-reference), ISO 2555 (Brookfield-method paint and ink), USP <911> (pharmacopoeial Brookfield method). Reference values: water = 1 cP at 20 °C (the famous calibration baseline; viscosity standards are sold traceable to NIST in mPa·s / cP units), SAE 10W30 motor oil at 100 °C ~12 cP, latex paint 500-1,500 cP, ketchup ~50,000 cP (highly shear-thinning so the exact number depends on shear rate).

About Millipascal-second (mPa·s)

A metric dynamic-viscosity unit equal to exactly 0.001 Pa·s, numerically identical to the CGS centipoise (1 mPa·s ≡ 1 cP exactly). The mPa·s is the most convenient working unit for water-like fluids and dilute aqueous solutions because water at 20 °C is essentially exactly 1 mPa·s — making the unit memorable and the conversion to viscosity ratios trivial. mPa·s is the universal reporting unit in: pharmacopoeial monographs (USP <911>, EP, JP) for ophthalmic solutions, parenteral preparations, and oral suspensions; clinical-laboratory biology and hematology (blood plasma 1.2-1.6 mPa·s, whole blood 3-4 mPa·s at body temperature — a clinically important parameter in stroke, sepsis, and polycythemia diagnostics); coatings industry rheometers reporting under ASTM D2196; printing-ink developers (ASTM D4287); food industry for fruit juices, syrups, dairy. Beer wort and finished beer 1.5-2.5 mPa·s; milk 2-3 mPa·s; honey 2,000-10,000 mPa·s.

Understanding Centipoise

The Centipoise (symbol: cP) is a unit of dynamic viscosity. A CGS dynamic-viscosity unit equal to exactly 0.01 poise = 0.001 Pa·s = 1 mPa·s. Centipoise is the traditional working unit in coatings, paints, petroleum products, food processing, and pharmaceutical excipient characterization — Brookfield rotational viscometers (the industry-standard QC instrument since the 1930s) default to reporting in cP on the dial readout. Test methods: ASTM D445 (kinematic viscosity, but cross-references to cP via density), ASTM D2196 (rheological properties via rotational viscometer), ASTM D562 (Stormer viscometer Krebs Units, with cP cross-reference), ISO 2555 (Brookfield-method paint and ink), USP <911> (pharmacopoeial Brookfield method). Reference values: water = 1 cP at 20 °C (the famous calibration baseline; viscosity standards are sold traceable to NIST in mPa·s / cP units), SAE 10W30 motor oil at 100 °C ~12 cP, latex paint 500-1,500 cP, ketchup ~50,000 cP (highly shear-thinning so the exact number depends on shear rate).

It belongs to the metric measurement system.

Centipoise are commonly used in lubricant selection, chemical processing, and fluid dynamics.

Understanding Millipascal-seconds

The Millipascal-second (symbol: mPa·s) is a unit of dynamic viscosity. A metric dynamic-viscosity unit equal to exactly 0.001 Pa·s, numerically identical to the CGS centipoise (1 mPa·s ≡ 1 cP exactly). The mPa·s is the most convenient working unit for water-like fluids and dilute aqueous solutions because water at 20 °C is essentially exactly 1 mPa·s — making the unit memorable and the conversion to viscosity ratios trivial. mPa·s is the universal reporting unit in: pharmacopoeial monographs (USP <911>, EP, JP) for ophthalmic solutions, parenteral preparations, and oral suspensions; clinical-laboratory biology and hematology (blood plasma 1.2-1.6 mPa·s, whole blood 3-4 mPa·s at body temperature — a clinically important parameter in stroke, sepsis, and polycythemia diagnostics); coatings industry rheometers reporting under ASTM D2196; printing-ink developers (ASTM D4287); food industry for fruit juices, syrups, dairy.
