You should also know how to solve problems using dimensional analysis Dimensional Analysis –Method of problem solving that focuses on the units & uses conversion factors The same thing as multiplying by a factor of one

How to use dimensional analysis 1.2 mg  g

Convert 1.2 mg  g6.3 cm  mm

5.12 m  cm12 L  g

6.11 mL  L1km  mm

1.03 kg  cg0.003 g  kg

428 cm 3  mL12 L  g

4 Liters/hour  mL/min
