Multiply numbers by 5.

Halve these numbers.

depending on whether it's 50R at 0 degrees C or at 25 degrees C.

There may be others based on 75F or something.

Copper RTDs are all over place in terms of the quoted resistance (and  therefore the tempco) when you get down to the last decimal place or  two, AFAIK there is no standard.

One of the main applications would be homemade with a bit of wire left over
from winding the motor, so annealing and exact composition would be  questionable.
