I think you got your units wrong. According to what I found on the
Internet, the standard is based on 100 degrees Celsius / 0 degrees
Celsius, which is 32 degrees Fahrenheit / 212 degrees Fahrenheit. Which
makes sense: it is commonly used for this type of ratings, because 0° is
water freezing point and 100° is water boiling point.

Orma & others,
With the SAE viscosity index, so called multi-grade oils are blended to be
equivalent to single grade oils at 2 different temps 100 degrees F and 32
degrees F.
Example: 5W30 would be equal in viscosity to strait 30 at 100 degrees and
equal to strait 5 at 32 degrees.
Hope this helps
