There isn't really any direct or proportional correlation between the two
measurement methods (in the same way as there is between metric and imperial
for example) as the paste is stressed in different ways.
The Malcolm method is preferred as this technique is closer to the way in
which the paste is actually used. I suggest that the Malcolm number be
regarded as definitive and the Brookfield numbers, if still given, should be
regarded as an indicator for historical continuity to older products.

Dear all,
The above reading was observed in test report and in datasheet respectively.
This is spec of solder paste viscosity of XXX manufacturer. What is the
correlation between the two viscometers readings and is there any
relationship between the two.
