![]() The digit that’s considered “most significant” is the one on the leftmost position.But if you want to perform all of the calculations manually, then you should know the basic rules for rounding numeric values: ![]() When it comes to significant figures, using any kind of sig fig calculators such as a multiplying significant figures calculator or a rounding significant figures calculator makes your job a lot easier. How do you round to 3 significant figures? Using the same example, you can’t remove the 3 zeroes unless you’re changing the number into scientific notation. The reason for this is that removing these non-significant numbers may have an effect on the number’s value. In some cases, zeroes found at the end of any given number aren’t significant but aren’t removed either. For instance, if you have the number 432,500 and you only need 3 significant figures, then you can round it off to 433,000. If a number contains more significant digits than what’s needed, you may round off that number.
