Conversion factor and equation set up

Goal: Be able to use conversion factors to convert data

Must know Conversions 1000 units = 1 kilo-unit 1 unit = 10 deci-units 1 unit = 100 centi-units 1 unit = 1000 milli-units 1 unit = 1,000,000,000 or 109 nano-units A units is any SI base unit like: gram, liters, meter Kilogram is actually the base unit for mass

Set up Conversion Factor Always start with the gicen Draw a times and a line (X--------------) Place units first- “bury” the old, unwanted unit on the bottom, the new unit is on top Insert numbers from the conversion factor w/ the appropriate units Repeat 3&4 if it takes multiple steps to get to the desired unit Do math using one of these 2 methods Multiply all numbers that are on top, then divide by the number(s) on the bottom Solve for each fraction then multiply them together Make sure units and sig figs are correct in the final answer
