Unit conversion of MPA n / mm2 and kg / mm2 Please tell your friends how to change the above three units As long as the unit conversion is n / mm2 and kg / mm2
1MPa = 1000000pa, 1pA = 1n / m2
1kg/m2=0.098MPA
1MPa (MPA) = 10.2kg/cm2 (kg / cm2)
What does the viscosity of glue (CPS) represent?
Viscosity of glue (CPS)
The viscosity of the glue is measured by Brinell viscometer, and the unit is "CPS centipoise". The reading of the viscosity of the glue is generally between 300 and 30000 CPS. In water-soluble adhesives, the solid content does not determine the viscosity of the glue, but depends on the plasticizer, tackifier, etc. in the formula of the glue, which affects the viscosity value of the glue, The viscosity of water at 27 ℃ is "1"
Conversion of viscosity units
The unit of dynamic viscosity is pa.s
The standard unit of kinematic viscosity is m ^ 2 / s
The conversion relation is: kinematic viscosity = Dynamic Viscosity / density
The unit of density is kg / m ^ 3
I want to know if m ^ 2 / S = (Pa.s) / (kg / m ^ 3) is OK, especially if the units are unified
Viscosity units are "pa * s" and "poise"
1 poise = 1 g / (cm * s) = 0.1 PA * s
Poise: unit of viscosity in the centimeter gram second system. It was named in memory of the French scientist Jean Louis Poiseuille (1799-1869)

How to read CPS, CPS = MPa
How to convert these two units?
Dynamic viscosity: the internal friction produced by the relative motion of two layers of fluid with an area of 1 m2 and a distance of 1 m at the speed of 1 m / s. unit: Pa.s (Pa.s)
CPS is centipoise, MPa. S is millipasecond
1CPS=1mpa.s
