Metric is a base 10 system. Easy to calculate. Most of the time you read inches as a fraction. While you can reinvent the wheel just to suit your needs it won't be practical. You'll have to remember we are using a low level computer that has to do a lot of calculations on the fly as it is (changing coordinates into steps per cm) If you throw fractions into the mix, that's just something else to go wrong.

This is because there are 2.54 cm in 1 inch. The file was exported using a 1/1 scale.

I am 50 and always worked in fractions and decimals. Since I got into 3D printing I am learning metric and I really, really wish the U.S. had switched over to metric like they said they were going to when I was in grade school.

Sorry about the double post. I thought that I had deleted the first one. I guess not. Thanks for the replies. It sounds like it is time to conform or be cast out. Once again America is wrong thinking that it holds the high ground. That's why an earlier Mars mission inpacted the surface. One guy designing in mm's and another in inches. I'm going to buckle down and set Rhino up for mm's. Something new to learn and that's what it's all about.

No, it's just easier for humans because we inherently understand decimal. A computer doesn't do integer, float, or decimal arithmetic in base 10 anyways. It's just the ending result that is converted back to what we understand, base 10.Quote

The answer is simple honestly.
Certain industries adapted one system globaly.
metric = just about every machined or produced article. Even cars built in the US use metric threads/bolts/nuts.
Standard = tiles, plumbing, and certain agricultural equipment.
The world is a mishmosh. At least we are down to small variations that are at least defined. Go look at mpg on a vehicle in the UK and a vehicle in the US. Same car gets higher MPG, the reason? The MPG standard in the UK is different than US.

If you can't handle working with both units, you might not be cut out to be in manufacturing/engineering. It's pretty obvious when something is 1mm vs 1 inch...

Uh I work in a very large machine shop and we program everything in decimal inch and every other shop I have worked at used decimal inch. Using metric fasteners does not mean the item was produced with a metric print. Anything we share with other countries is done with dual dimensions.
