I don't know exactly what you are trying to determine, but the referecned article might be interesting.
NASA Programmers were using 22/7 for PI (3.1428571) which if you compare to a six decimal place equilvalent of 3.14159 is .0004% different.
Which may be interesting in that it's not only what the scientist calculated but what was used in the design of the actual controls and software.

There are no 'units' for PI. Therefore, it is neither metric or english.
