5. Count the number of digits from the first non-zero digit to the last non-zero digit.
1,2,3,4,5,6,7,8,9
In this case, where there are no non-zero digits to the left of the decimal point, the number of significant figures is equal to the number of digits to the right of the decimal point from the rightmost figure to leftmost non-zero digit. In this case, there are four significant digits
Five significant digits. Remember that all non-zero digits are significant, and all zeros in-between significant digits are significant.
One fewer than the base for the number system.
5. Count the number of digits from the first non-zero digit to the last non-zero digit.
All of the digits are significant digits in this case. A zero between other (non-zero) digits is considered significant.

How many
To count significant figures, you count all the non-zero digits. You also count zeros which are between non-zero digits, as well as zeros which are after the decimal point, only if they appear to the right of non-zero digits.
If there are no non-zero digits, the value is zero.
Because this number does not have a decimal point, to count significant digits, we start at the right and start counting from the first non zero number. The first non zero number is 6 and this number has 4 significant digits.
In this case, where there are no non-zero digits to the left of the decimal point, the number of significant figures is equal to the number of digits to the right of the decimal point from the rightmost figure to leftmost non-zero digit. In this case, there are four significant digits
There are three sig fig in 0.00567. The first significant figure is the first non-zero digit; count all the digits from there ontwards until the last non-zero digit is reached.
Five significant digits. Remember that all non-zero digits are significant, and all zeros in-between significant digits are significant.

5 of them. All non-zero digits are considered significant. Zeros appearing anywhere between two non-zero digits are significant. Leading zeros are not significant.
