Millimeters to Inches Conversion – How Accurate Do I Need to Be?

Hey everyone,

I have a quick question regarding the Millimeters to Inches Conversion. I’m working on a project where I need to convert a few measurements, and I keep getting a little confused.

I know the standard conversion factor is 1 inch = 25.4 millimeters, but I’m unsure of how precise I need to be for my calculations. Is it generally acceptable to round the conversion factor to 25 or 25.5, or should I stick strictly to 25.4 for accuracy?

Any advice or tips on conversions would be greatly appreciated!

Thanks!
