Start with the measurement you are dealing with. Multiply by the appropriate conversion factor using all the decimal places. If there is more than one choice of conversion factor, use the one that is closest in comparison (i.e., pounds and kilograms rather than pounds and grams, or feet and meters rather than feet and centimeters). In general, round the answer to the same number of places after the decimal you had in the original number. Otherwise, use your judgment.
There are a number of Web sites that can do the conversions for you. Here is a list of some helpful sites:
