                                      Conversion of Metric Measure units of Length, Weight, Capacity

               To convert a bigger unit to a smaller unit, we multiply.

                                 ×10          ×10          ×10          ×10         ×10          ×10

                                 ÷10          ÷10          ÷10          ÷10         ÷10          ÷10
               To convert a smaller unit to a bigger unit, we divide.
