Python- Metric to SAE Math

Question

Working on python math to convert Metric Socket to SAE (Society of Automotive Engineers) sockets. My code
mm = float(input("Enter Socket MM: "))
round(mm*0.39216,2)
output
Enter Socket MM: 13
I get 5.1
hoping for
13mm == 0.531
upon building on the above answer of 0.531 then want the code print out
SAE equivalent 17/32 socket
Thanks

Answer 1

Sounds like an interesting project.
This should get you started

import math

mm = float(input())
sae = round(mm * 0.03937,3)
print(sae)

print(f"{math.ceil(32 * sae)}/32")
