How many significant figures are in 100?

Answer 1

If you are looking at this from a maths perspective, the 'significant figures' are the number of digits counting from the first non-zero digit, so the number of significant figures in 10.0 is three.

You may be asked a question, and told to give the answer 'to three significant figures'. This would mean the answer would look something like '12.2' or '0.0254'.

This is in contrast to decimal places, which refer to the number of digits after the decimal point. For example, the number 10.0 is quoted to one decimal place.
