Hello,
I need your help with an argument I got myslef into. I may be wrong here due to old information but bare with me and see if you can help me out.
I am a designer for an engineering firm and I posted a response in a CAD forum in regards to converting inches to cm or mm. Since I did not know what this person was drafting I posted that 1" = 25.3995mm. This was found in an old math book from the 1950's that had a conversion table in the back of it (yes I typed old - I know old sources are never the best thing to quote - my mistake).
The industry standard seems to be 1" = 25.4mm and in the link here THIS LINK post's that "1in = 2.54cm (exactly)". I was baffled by "exactly", considering that I was under the impression that nothing is exact in this world so we just have to settle for dam close.
Is there any information that supports my post that 1" = 25.3995mm? Please help!!
Let me know if you need clarification...
