Rules Governing Significant Figures

All non-zero digits are significant. : 

All non-zero digits are significant. Example: 1.234 kg. has four significant figures.

Zeroes between two non-zero digits are significant. : 

Zeroes between two non-zero digits are significant. Example: 40.507 cm. has five significant figures.

Zeroes to the left of the first non-zero digits are not significant. : 

Zeroes to the left of the first non-zero digits are not significant. Example: 0.009 has only one significant figure.

If a number is greater than one all zeroes to the right of the decimal point are significant. : 

If a number is greater than one all zeroes to the right of the decimal point are significant. Example: 7.000 has four sf. 4005.0 has five sf.

If a number is less than 1, only the zeroes at the end of the number and zeroes between two non-zero digits are significant. : 

If a number is less than 1, only the zeroes at the end of the number and zeroes between two non-zero digits are significant. Example: 0.02010 has four significant figures.

The zeroes immediately to the left of an unexpressed decimal point are not significant. : 

The zeroes immediately to the left of an unexpressed decimal point are not significant. Example: 400 has one sf.

Rounding-off numbers to Significant Figures : 

Rounding-off numbers to Significant Figures

If the first non-significant digit is less than 5, then the least significant digit remains unchanged. : 

If the first non-significant digit is less than 5, then the least significant digit remains unchanged.

If the first non-significant digit is greater than 5, the least significant digit is incremented by 1. : 

If the first non-significant digit is greater than 5, the least significant digit is incremented by 1.

If the first non-significant digit is 5, the least significant digit can either be incremented or left unchanged : 

If the first non-significant digit is 5, the least significant digit can either be incremented or left unchanged

All non-significant digits are removed. :
