This tool converts between dynamic viscosity units using fixed conversion factors, for example, 1 poise equals 0.1 pascal-seconds, and 1 centipoise is numerically equal to 1 millipascal-second. Enter a value in any supported unit and it's converted to all others using these standard ratios.
Pascal-seconds (and millipascal-seconds) are the SI standard, common in engineering and scientific contexts. Poise and centipoise are cgs units still widely used in industry and material data sheets, water at room temperature has a viscosity of almost exactly 1 centipoise, making it a handy reference point.
Converting 1 poise to centipoise gives exactly 100 cP (1 poise = 0.1 Pa·s = 100 mPa·s = 100 cP), so a material data sheet listing a fluid's viscosity as, say, 5 poise translates directly to 500 cP, roughly 500 times more viscous than water at room temperature.
Confusing dynamic viscosity (this converter, resistance to flow under an applied force) with kinematic viscosity (dynamic viscosity divided by density, measured in units like centistokes), material data sheets sometimes report one or the other, and they aren't interchangeable without knowing the fluid's density.
Assuming viscosity is temperature-independent, most fluids (like motor oil) become noticeably less viscous when heated, a data sheet value is only valid at the specific temperature it was measured at.
Mixing up poise and pascal-seconds by an order of 10 rather than the correct factor, 1 poise equals 0.1 Pa·s, not 1 Pa·s, worth double-checking on any calculation that depends on getting this right.
Divide centipoise by 1,000 to get pascal-seconds, or use this converter for an instant result.
Water at about 20°C (68°F) has a viscosity of approximately 1 centipoise (1 millipascal-second), commonly used as a reference point when comparing other fluids.
