By the way !
in the practical when they say in the beginning of the experiment take the length of the rope of ABOUT 50cm
does that mean we have to take 50 or there is some sort of range?

if the uncertainity is 18.0 + or - 0.05 mm

nope..if u've got all the values in one unit...then no need to change as long as u mention +- mm, m, cm, etc..
