HP 12C (Metric to Standard Conversion)

[Gamo]

Thanks Dieter
I'm only amateur and start to play around with this HP 12C program and your advice is very welcome.
I though that the four digits fraction will get 9 decimal accuracy internally so I used fraction (make division) instead of using specific fix number. I try to check all the units and it give accuracy above 6 decimal place.
