Homework Statement

i suspect the possible error of 100cm/192cm = 1m /192 m is wrong , IMO , it should be 1m /1.92m , right ?

100cm/192cm

It is not 100cm/192cm. It is (100/192) cm, which is (1/192) m.

It is not 100cm/192cm. It is (100/192) cm, which is (1/192) m.

why ? i still didnt get it ? could you explain further ?

why not (1 / 1.92 ) m ?

It is not a fractional error, like 100 parts in 192 parts, which would be over 50%. It is an absolute error of the distance (100/192)cm, or a bit over 0.5cm. Why they would choose to express it that way I have no idea.

Because that would be over 50cm, 100 times the error.

do you mean it's 100/192 = 0.52cm = 0.0052m (1/192) ?

Yes.
