It gives advice on how to use and write metric units mistak es to avoid what to do about conversions and wher e to find further information A brief explanation of how th e metric system works is also given Basic rules Capitals and lower case Names o Why do scientists need a standard system of measurements?. Remember that science must be . repeatable. – another scientist has to able to repeat your experiment using the same amounts, concentrations, lengths, weights, etc.. The properties of matter must be measured correctly and reported without ambiguity. . Value- A quantities description that includes both a number and a unit. Units- quantities defined by standards that people have agreed to use to compare one event/object to another. . Long Ago…. . Parts of the human body were often used to measure.
