5x4.5 = 5x115mm .. right?

Like a few others here I'm looking for either 16"-17" rims for my 73 dart with big bolt pattern.

I was looking at some aftermarket rims made for a newer Chrysler 300. The bolt pattern is 5x115mm, which converted = 5x4.5inch; right?

4.5 inches converts to 114.3mm...so if you're going from 5x115mm, it would convert to 5x4.53....not sure if that makes a difference, or a headache, sorry.
