For example, if we decide unit length to be 1 meter, and if a length of the side of the table is 1.5 meters then magnitude of the measurement is 1.5.
(we; decide; unit length to be 1 meter) (unit length; to be; 1 meter) (a length of the side of the table; is; 1.5 meters; T:then) (magnitude of the measurement; is; 1.5)
we unit length a length of the side of the table magnitude of the measurement
decide to be is is
unit length to be 1 meter
1 meter
1.5 meters T:then
1.5
