6. Converting Within Metric Units
Good to Know
1 kg= 1000 g
1 g = 1000mg
1 mg= 1000 mcg
1 L= 1000 mL
Dividing or Multiplying by 1000 gets determined by size of unit
Ex.
100 ml L smaller to larger

7. Fact to Remember Zero in front of the decimal when less than 1
ALWAYS (should) have a label of measurement
Convert fractions to decimals
Be careful when writing abbreviations , state clearly what the unit is
