How do you determine the wt. and viscosity of industrial oil?

A lube oil that is 20 deg API or 20 wt. is written on the can. To convert that to specific gravity (SG) you use the following form





API=141.5/SG-131.5


or


SG=141.5/(API+131.5)





API=20 for example





SG=141.5/(20+131.5)





SG=141.5/151.5





SG=0.93





The viscosity can be found in the MSDSHow do you determine the wt. and viscosity of industrial oil?
Look at the front of the can. It says on the front.
