ABOVE: question 2.b) pg.138

I found it really difficult to understand how to do the caliper measurement in imperial units.  I researched and asked for help.

An inch in imperial units is divided in 16 parts and within those parts its divided in 32 and then 64, just multiplying by 2 starting with 4.

So when we are reading the course reading which is the main “ruler” the one that doesn’t move in the middle we have to read it as a fraction of a inch. its two measurements ( the course and then the vernier) that we have to find out and then add together to get our total measurement.

understanding that we cant mix the metric which is centimeter and millimeters and the imperial which is fractions.
