10 10 10-6 In micro You can use these relationships to create equalities and conversion factors. For example, the prefix dea is denoted with a d and is associated with a factor of 10- If you were to apply this profix to liter, you would obtain the equality 1 dL -10 L. This could be used to create two conversion factors: 1 dL 10-1 L 10-1 The conversion factor used will depend on whether the final unit should be in...
