Question 486084
<font face="Times New Roman" size="+2">


One Kilometer is approximately 0.621371192 miles.  Your given value is 3 decimal place accuracy.  If you are using a calculator, just multiply the conversion factor by 0.347 and then round the result to 3 decimal places.  (Never, never, never present the result of a calculation involving measurements to greater precision than the <i>least</i> precise given measurement.)


If you are doing the calculation by hand, first round the conversion factor to four decimal places, do the multiplication, and then round the result to three places.  No point in doing a bunch of intermediate multiplication steps that will have no effect on the final outcome.
