According to the wikipedia article about it, it was the yard that got defined as 0.9144 m, which resulted in the 2.54 cm inch.
For any actual use it doesn't matter.
I think I know were the number in the result came from, but I have not idea where that formula came from, it is really messed up.
(1/0.3937*36*1760)/160934.4 = 1.000002000004000008000016000032000064 . . . cute decimal expansion BTW.
With units
((1/(0.3937 in/cm))*((36*1760)in/mile))/160934.4cm = 1.000002... mile
-1
1.000002 is definitely a possible answer I will include from now on in any multiple choice exam I get to write where the question is how many miles is 1.609344 km
0.999998 will be another.
The last three will be 1, 3.14159 and rhubarb.
