How do you determine the number of significant figures in each measurement?
To determine the number of significant figures in a number use the following 3 rules:
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.

How do you measure a rectangle with three significant figures?
We say that the measurement is reported to three significant figures. The rectangle is at least 1.0 cm wide but certainly not 2.0 cm wide, so the first significant digit is 1. The rectangle’s width is past the second tick mark but not the third; if each tick mark represents 0.1, then the rectangle is at least 0.2 in the next significant digit.
How many significant figures does the number 12 have?
Similarly, 1 foot (ft) is defined to contain 12 inches (in), so the number 12 in the following equation has infinitely many significant figures. Give the number of significant figures in each. Identify the rule for each.
