🫗 Dynamic Viscosity Converter

Convert dynamic viscosity units — pascal-second, millipascal-second, poise, centipoise and micropoise. Water is about 1 cP; 1 poise = 0.1 Pa·s.

From

1 Pa·s = 1000 mPa·s

Precision

1 pascal-seconds = 1000 millipascal-seconds

1 × 1000 = 1000

1 Pa·s equals 1000 mPa·s, so multiplying by 1000 converts the value. The result describes the exact same quantity — only the measuring stick changes.

Unit	Symbol	Definition
Pascal-second	Pa·s	The SI unit of dynamic viscosity — one pascal of shear stress producing a velocity gradient of one per second. Water is about 0.001 Pa·s; honey is a few Pa·s.
Millipascal-second	mPa·s	One-thousandth of a pascal-second (10⁻³ Pa·s), numerically identical to the centipoise. The everyday unit for thin liquids — water at 20 °C is almost exactly 1 mPa·s.
Poise	P	The CGS unit of dynamic viscosity, exactly 0.1 Pa·s. Named after Poiseuille; still common in older fluid-mechanics and lubricant literature.
Centipoise	cP	One-hundredth of a poise, equal to 1 mPa·s. The most-used practical unit — water is ~1 cP, motor oil tens to hundreds, honey around 10,000 cP.
Micropoise	µP	One-millionth of a poise (10⁻⁷ Pa·s). Suited to very low viscosities such as gases — air is about 180 µP.
