# Do you count all zeros behind a decimal place as significant figures?

##### 1 Answer

No.

#### Explanation:

Not all zeroes. There are some rules for zeroes:

If a zero is behind a decimal and is trailing a non-zero, then it is significant. E.g. 5.00 - 3 significant figures.

If a zero is leading a number, before or after the decimal, it is **not** significant. E.g. 0.00849 - 3 significant figures.

If a zero is trailing a non-zero digit, but it is **not behind a decimal**, it is not significant. E.g. 4500 - 2 significant figures.

Hope this helps :)
