Hello,
Does anyone know how to convert the viscosity of fuel oils in Redwood number seconds to centi-stokes?

RE: Converting viscosity - Redwood to cSt
You also need the density of the product.
In any case its easiest to do it here,

Of course if you want to convert from kinematic to dynamic (also called absolute) or vice versa then you must know the density.

RE: Converting viscosity - Redwood to cSt
The conversions by calculators or from nomographs or tables are only approximate. At the low viscosity ranges, 10 cSt and lower, errors may be quite large. Formulas I found, based on actual measurements, are:
for Redwood #1,
cSt = 0.260 R - 179/R for 34 ≤ R ≤ 100 seconds
cSt = 0.247 R - 50/R for R > 100 seconds
for Redwood #2 (Admiralty)
cSt = 2.458 R - 100/R for 32.5 ≤ R ≤ 90 seconds
cSt = 2.447 R for R > 90 seconds

Thank you all, you have solved my problem.
Many thanks,
