Is there an equation that relates viscosity of water to temperature? If not, is there a reliable table somewhere on the internet? I'm searching for the viscosity at 20°C ± 3°C.

Thanks!

The units of viscosity is Pa*s or kg/(m*s)

Pa*s = N*s/m^2 = kg*(m^2/s)/m^2 = kg/s

??
 
pascal = N/m^2 = J/m^3 = kg/(m·s^2)
