On the back of my digital callipers there is a table (photo attached). What do the various columns and numbers signify?

Why are they on the callipers and height gauges?


Thanks,
Ken

They've been on for as long as I can remember and Whitworth (BSW and BSF) was supposed to be made redundant years ago.

Explanation? Old habits die hard and/or nobody has ever bothered to complain.

I once had some made that gave ISO h8 and H8 tolerances for shafts and holes.
