Example: Known viscosity 60 cSt at 50°C (K). The following can
be read along the dotted line: viscosity at 80°C = 20 cSt, tempera-
ture at fuel injection pumps 74-87°C, centrifuging temperature
86°C, minimum storage tank temperature 28°C.
Conversion from varies current and obsolete viscosity units to
centistokes can be made in the diagram, Fig 02-2. The diagram
should be used only for conversion of viscosities at the same
temperature. The same temperatures should then be used when
entering the viscosity/temperature point into the diagram, Fig
02-1.
Viscosity conversion diagram
When converting viscosities from one of the units on the abscissa
to centistokes or vice-versa, keep in mind that the result obtained
is valid only at one and the same temperature. When converting
the viscosity in any unit at a given temperature to a viscosity at
another temperature a viscosity-temperature diagram or conver-
sion rule must be used.
