Dimensional Analysis Calculations with More than 2 Steps Day 2 - Notes Dimensional Analysis Calculations with More than 2 Steps

Example How many seconds are in 1.50 weeks? 1.50wk 7days 24hrs 60min K: 1.50weeks U: ? sec wk  days  hours  minutes  seconds 1 wk=7days 1 day=24hr 1 hr=60min 1 min=60sec 1.50wk 7days 24hrs 60min 60sec x x x x 1 1wk 1day 1hr 1min = 907,000sec

Two new conversion factors you must know: 1 inch = 2.54cm 1 mile = 5,280ft

Example The Empire State building is approximately 381 meters high. How many miles high is the Empire State building? K: 381m U: ? mi m  cm  in  ft  mi 1m=100cm 2.54cm=1in 12in=1ft 5,280ft=1mi 381m 1in 1ft 1mile 100cm x x x x 1 1m 2,54cm 12in 5,280ft = 0.237 mile
