Been measuring wrong whole time?
Hi I think I been measuring incorrectly because I been using tape measure. With tape measure I’m 7.5NBPEL and 7 3/4 BPEL(almost 8 inches) with a ruler I’m only 7.5 BPEL and a little over 7NBPEL. Why is there such a difference is it because of the ruler?
I have found this online:
“If it is a school type ruler which does not have zero at the end of the ruler then yes you have two measurements as above. If it is an engineer’s rule with zero flush ground to one end then there is only one comparison to account for.
My rulers do not have zeros on the left side so I feel I’m losing length.
Correct me if I’m wrong.
