Projects Programming
1

I am trying to do the following

calculated:
1 thou = 1000th of an inch
39th = 1.016mm

I am having problems with converting this file to metric co-ords. I would like to complete the conversion to metric on a SD card a delete the imperial format or, make a new sub directory to save new data.

I am having problems with converting this file to metric co-ords

And those problems are what, exactly?

3

were origin X Y becomes negative value.

4

Gates:
were origin X Y becomes negative value.

Signs are different in metric and imperial?

5 
Returns mil in mm with 4 digits fixed decimal point
long milToMm(int mil){
  return 254L * mil;
}
6

One inch is defined as 25.4 millimetres.

...R

7

Robin2:
One inch is defined as 25.4 millimetres.

...R

Which is a helluva lot more precise than "three grains of barley, dry and round, placed end to end, lengthwise".

8

AWOL:
Which is a helluva lot more precise than "three grains of barley, dry and round, placed end to end, lengthwise".

I was just thinking that it is easy to use in calculations :slight_smile:
