    • Improve the accuracy of measurements and calculations

      • Significant digits are the digits in a measurement that are known to be reliable and certain. They are the digits that are known to be accurate, while the remaining digits are considered uncertain or approximate. In other words, significant digits represent the precision of a measurement, while the non-significant digits represent the uncertainty. For example, the measurement 3.45 meters has three significant digits, while 3.4500 meters has five significant digits.
