Significant figures are basically the amount of digits in a number.


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.


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.
