Factor-label method help This site has more instruction on the more difficult conversion problems. It is set up in a nice way, allowing you to think about the solution and then click on a button to reveal the solution. Significant figures help This site has an excellent summary of the rules for significant figures as well as examples of how to use them. Ignore their discussion of rounding, however, as they are wrong. In science, we do not round when the number being dropped is 0-4, and we round up when the number being dropped is 5-9. Although they claim that dropping a zero does not change the value of the number, that is only true when EVERY digit you drop is zero. Dropping the last three digits in 5.1045 does, indeed, change the value of the number despite the fact that the first number you drop is a zero. In terms of the number line, when you do not round on 0-4 and round up on 5-9, you are statistically rounding up as often as you are rounding down.
