To figure out how many significant figures there are in a number you must first know the rules. All numbers 1-9 are counted towards the number of significant figures. The only number you need to worry about is 0.
-If there are 0's between digits (like 105), they are counted towards sig figs.
-If, to the right of a decimal point, the number ends in a 0 (4.660), the 0 counts towards sig figs.
-If, to the left of a decimal point, the number ends in 0 (4500), the 0 (or this case zeros) do not count towards sig figs.
-If there is a lone 0 to the left of a decimal point (0.112), the 0 does not count towards sig figs.
Now this case is simple, because there are no zeros. There are 2 significant figures in 4.5 meters.

How many yards are there in 45 millimetres?
There are 914.4 millimetres in one yard. Therefore, rounded to three significant figures, 45 millimetres is equal to 45/914.4 = 0.0492 yards.
What is the differences between a significant figure and decimal place?
A decminal place is simply the number of digits to the right of the decimal in a number. For instance, 37.5834 has four decimal places. In contrast, a significant figure is the number of digits on either side of the decimal place that can be counted as accurate in a calculation. Significant figures are used to determine how accurate a calculation is based on how accurate the measurements are. Significant figures are determined by counting the number of significant figures in the numbers given in a problem (usually in chemistry or physics) then using the lowest count found. Here's an example: "calculate the average velocity of a car that has travelled 45 km in 60 minutes." The number "45" has two significant figures while the number "60" has one significant figure. Therefore, when calculating the velocity (45/60), the answer can have only one significant figure: 0.8 km/min. However, if the time was written as "60.0" minutes, then this number would have three significant figures and the answer could have two significant figures (0.75 km/min) because the number "45" had two significant figures.
