Viscosity calculator

exactly on the milliliter

Viscosity is a measure of the resistance of a fluid to being deformed by either shear stress or extensional stress. It is commonly perceived as “thickness”, or resistance to flow. Viscosity describes a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction.
Density: g cm-3


  • Dynamic viscosity:

    N s m-2 = kg m-1 s-1 = Pa s

    dyn s cm-2 = g cm-1 s-1 = Poise

    cp, centipoise = m Pas

    kg m-1 h-1

    lb ft-1 s-1 = pdl s ft-2

    lb in-1 s-1

  • Kinematic viscosity:

    cm2/s, stoke, square centimeter per second


    mm2/s, cstoke, square milimeter per second


    m2/h, square meter per hour


    in2/s, square inches per second


    ft2/s, square foot per second

    ft2/h, square foot per hour
