Q: How do we convert between US and metric measurements? Using DIMENSIONAL ANALYSIS!

Rules for Conversions Step 1: Step 2: Circle what you are looking for in the problem and underline what you are given. Always start by writing down what you know (what are you given?) Step 2: Draw your grid and set up the units If a unit was previously on top, it must go on the bottom to cancel

Rules for Conversions Step 3: Step 4: Place the numbers in the appropriate spot as given on the reference sheet Step 4: Cancel the units, complete the math multiplying ALL the top numbers together multiplying ALL the bottom numbers together divide your top answer by your bottom answer

EXAMPLES How many feet are in 100 centimeters? How many oz are in 10 mL? How many kg are in 180 lbs?
