Define unit of measure of a number

[doug2019]

I would like a function or command to define the unit of measure, either MPa (10 ^ 6) or GPa (10 ^ 9).e.g
20,000,000,000.00 > 20GPa
5,000,000.00 > 5MPa

And how might you expect that to look like in code?

1 2 3 4 5 6 7 8 9 10 11 12

def transform(x):     if x < gpa:         return(str(int(x/mpa))+"MPa")     elif x >= gpa:         return(str(int(x/gpa))+"GPa")   gpa=1000000000 mpa=1000000 value1= 20000000000 value2= 5000000 print(f"{value1} > {transform(value1)}") print(f"{value2} > {transform(value2)}")

Output:
20000000000 > 20GPa
5000000 > 5MPa

This would also be simple enough to do as a lambda function:

1 2 3 4 5 6 7

g = lambda x : str(x/1000000)+' MPa' if x<1000000000 else str(x/1000000000)+' GPa'   value1= 20000000000 value2= 5000000   print (g(value1)) print (g(value2))
