Simple units conversion question

[QUOTE="berkeman, post: 6168508, member: 8921"] As shown by [USER=237160]@phyzguy[/USER] it is best to carry units along in your calculations. Units on the LHS and RHS of each equation should match. A helpful trick for doing units conversions is to "multiply by one", where the "one" has the units you want to end up with in the numerator, and the units you want to cancel out in the denominator. Like this: Convert 60 km/hr into m/s: [tex]1 = 3600 \frac{s}{hr} = 60 \frac{s}{min} * 60 \frac{min}{hr}[/tex] [tex] 60 \frac{km}{hr} * \frac{1 hr}{3600 sec} * \frac{1000 m}{1 km} = 16.7 m/s[/tex] [/QUOTE]
