Unit Conversions The main units can be scaled up or down using prefixes on page 20. Click here for "Powers of Ten" Video

Unit Conversions Example: How many milliliters (mL) of soda are in a 2.0 liter (L) bottle? 2.0 L1000 mL 1 L = 2000 mL Dimensional Analysis…or “Bridge Problems” Conversion Factor is equal to one!

Unit Conversions Example: How many kilograms (kg) are there in 100 milligrams (mg)? 100 mg 1 g 1000 mg = 0.0001 kg 1 kg 1000 g
