What is SSU viscosity unit?
SSU viscosity means the number of seconds it takes 60 cubic centimeters of an oil to flow through the standard orifice of a Saybolt Universal viscometer at 100 degrees Fahrenheit.
What is a centistoke equal to?
Kinematic viscosity is often measured in the CGS unit centistokes (cSt), which is equivalent to 0.01 stokes (St).
How do I convert to cP?
An easy way to convert from kinematic to dynamic viscosity is to multiply the value in centistokes by the specific gravity of the liquid to get the corresponding value in centipoise.
How do you convert centistoke to centipoise?
Centipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120).
How do you convert viscosity to centipoise?
Viscosity Conversion Centipoise (cP) = Centistokes (cSt) x S.G.
What is the viscosity of water in SSU?

Viscosity of some Common Liquids
| centiStokes (cSt, 10-6 m2/s, mm2/s) | Saybolt Second Universal (SSU, SUS) | Typical liquid |
|---|---|---|
| 1 | 31 | Water (20oC) |
| 4.3 | 40 | Milk SAE 20 Crankcase Oil SAE 75 Gear Oil |
| 15.7 | 80 | No. 4 fuel oil |
| 20.6 | 100 | Cream |
What is mPas in viscosity?
Measurement units of viscosity The measurement unit of viscosity is Pa·s (pascal second) or mPa·s (millipascal second). As viscosity value increases, the force due to viscosity increases as well. In addition, cP (centipoise) is the conventional measurement unit.
How much is 1poise?
A centipoise is one hundredth of a poise, or one millipascal-second (mPa⋅s) in SI units (1 cP = 10−3 Pa⋅s = 1 mPa⋅s)….Poise (unit)
| poise | |
|---|---|
| 1 P in … | … is equal to … |
| CGS base units | 1 cm−1⋅g⋅s−1 |
| SI units | 0.1 Pa⋅s |
Is cP the same as cPs in viscosity?
A unit of measure of dynamic viscosity in the centimeter-gram-second system of units equal to one one-hundredth of a poise (1 P = 100 cP = 1 g x cm-1 x s-1). (The viscosity of water at 70 F is 1 centipoise. The lower the number, the less viscous the material.)
What does SSU mean for oil?
Sabolt Seconds Universal
The most common unit in the United States is the Sabolt Universal Seconds (SUS) or Sabolt Seconds Universal (SSU), which is measured with a Saybolt Viscosimeter. The tested oil is brought to 100° F and poured through a standard orifice of 0.0695 in. in diameter.
What does cP mean in viscosity?
centipoise
1. n. [Drilling Fluids] A unit of measurement for viscosity equivalent to one-hundredth of a poise and symbolized by cP. Viscosity is the ratio of shear stress to shear rate, giving the traditional unit of dyn-s/cm2 for Poise. In metric (SI) units, one cP is one millipascal-second (mPa.
