Viscosity Converter Calculator

Convert dynamic viscosity between pascal-second, poise, centipoise, and millipascal-second. The form asks for a Value, From unit, and To unit, then returns the chosen conversion and all supported units.

Viscosity measures resistance to flow, not the amount of fluid moving through a pipe. Water, oil, syrups, paints, and industrial fluids may be reported in different unit systems, so conversion helps compare specifications. For related fluid work, the flow rate converter, density converter, and temperature converter may be useful.

How to use this calculator

  1. Enter a nonnegative viscosity value.
  2. Select Pa⋅s, P, cP, or mPa⋅s as the starting unit.
  3. Select the target unit.
  4. Confirm the measurement temperature before comparing fluids.

Conversion formula

The calculator converts through Pa⋅s.

UnitFactor in Pa⋅s
1 Pa⋅s1
1 P0.1
1 cP0.001
1 mPa⋅s0.001

Worked example: 0.75 Pa⋅s ÷ 0.001 = 750 cP. Since cP equals mPa⋅s, the same value is 750 mPa⋅s.

Frequently asked questions

How many centipoise are in 1 Pa⋅s?
1 Pa⋅s equals 1000 cP.
Is cP the same as mPa⋅s?
Yes. In this calculator, 1 cP equals 1 mPa⋅s because both use a factor of 0.001 Pa⋅s.
How many poise are in 1 Pa⋅s?
1 Pa⋅s equals 10 P, and 1 P equals 0.1 Pa⋅s.
Why does temperature matter for viscosity?
Viscosity often changes strongly with temperature, so compare values measured at the same temperature and test conditions.
