A significant figure is basically counting how many digits there are: In this case this number is to FOUR significant figures because there are FOUR digits. Here's some more examples: When you have zero's in front of the number, these do not count as digits: so, if you had 0.0034, you only count the 3 and 4 as digits so this would be to TWO significant figures. However, if you have 0.003404, you must count the zero in between the two four's because this is part of the number - there are FOUR significant figures here.
