How to convert poises to millipascal-seconds P to mPas. Η mPas = 100 × η P. How many millipascal-seconds in a poise: If η P = 1 then η mPas = 100 × 1 = 100 mPas. How many millipascal-seconds in 44 poises: If η P = 44 then η mPas = 100 × 44 = 4 400 mPas.

DYNAMIC VISCOSITY

Poise (symbol: P) + centiPoise (symbol: cP)

Named after the French physician Jean Louis Marie Poiseuille (1799 – 1869), this is the CGS unit of viscosity, equivalent to dyne-second per square centimetre. It is the viscosity of a fluid in which a tangential force of 1 dyne per square centimetre maintains a difference in velocity of 1 centimetre per second between two parallel planes 1 centimetre apart.

Mpa To Cst Conversion

Even in relation to high-viscosity fluids, this unit is most usually encountered as the centipoise (cP), which is 0.01 poise. Many everyday fluids have viscosities between 0.5 and 1000 cP.

Pascal-second (symbol: Pa.s) + milliPascal-second (symbol: mPa.s)

This is the SI unit of viscosity, equivalent to newton-second per square metre (N·s m–2). It is sometimes referred to as the poiseuille (symbol Pl).

Centipoise

One poise is exactly 0.1 Pa·s. One poiseuille is 10 poise or 1000 cP, while 1 cP = 1 mPa·s (one millipascal-second).

KINEMATIC VISCOSITY

Viscosity Mpa To Centipoise

Stokes (symbol: St) + centiStokes (symbol: cSt)

This is the CGS unit, equivalent to square centimetres per second (cm2 s–1). One stokes is equal to the viscosity in poise divided by the density of the fluid in grams per cubic centimetre (g·cm–3). It is most usually encountered as the centistokes (cSt), equal to 0.01 stokes.

Saybolt Seconds Universal (SSU)

This is the time for 60 millilitres (ml) of fluid to flow through the calibrated orifice of a Saybolt Universal viscometer at a specified temperature, as prescribed by test method ASTM D 88. For higher viscosities, SSF (Saybolt Seconds Furol) is used. “Furol” comes from “fuel and road oil”.
