Significant figures are basically the amount of digits in a number. E.g. 2.576 has 4 significant figures 32.545 has 5 significant figures Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures. E.g. 0067.4 has 3 significant figures 67.400 has 3 significant figures 0067.400 has 3 significant figures. In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.
