Convert dynamic viscosity between centipoise, mPa·s, or poise and centistokes using specific gravity to find any missing value for fluids.

The centipoise reading from a rotational viscometer. 1 cP equals 1 mPa·s, and water is about 1 cP at room temperature.

The fluid density divided by the density of water. Dimensionless and close to the density in g/cm3. Water is 1.00.

The centistokes value. 1 cSt equals 1 mm2/s, often taken from an ISO VG grade at 40 C.

Centipoise measures dynamic viscosity and centistokes measures kinematic viscosity. The two are linked by specific gravity, so you need the fluid density to convert between them. When SG is 1.00 the two values are equal.

Centipoise To Centistokes Formula

The following formula is used to calculate the conversion from Centipoise to Centistokes.

CS = CP / SG

Variables:

  • CS is the Centistokes (cSt)
  • CP is the Centipoise (cP)
  • SG is the specific gravity (dimensionless)

To calculate the Centistokes, divide the Centipoise by the specific gravity.

What is a Centipoise To Centistokes?

Centipoise and Centistokes are units of measurement for viscosity, which is the measure of a fluid’s resistance to flow. The conversion from Centipoise to Centistokes involves the fluid’s specific gravity. Specifically, Centistokes equals Centipoise divided by the specific gravity of the fluid at a certain temperature. This conversion is important in various industries such as engineering and chemistry where understanding the flow characteristics of a fluid is crucial.
