Measurement is a hallmark of science, and you must communica
the precision of a measurement so that others know how reliab
the measurement is. When you write or manipulate measure
quantities, you must show and retain the precision with which t
original measurement was made.
The units in a measured quantity communicate what the quanti
actually is. Without an agreed-on system of units, scientists cou
Inits are also important
