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.

170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
1,000 m = 1 km If there is not decimal point at the end of 1000. it is just 1km. If there is a decimal point the correct significant figures would be 1.000 km
As a km is 1000 meters, you would divide the number of meters by 1000.DANDivide the number of metres by 1,000. The answer is the number of km.
4,777 km
The sum is: 1333 km
1 km = 0.6214 miles 8 miles ( 1km/0.6214 miles) = 12.8741551 km which according to the number of significant digits will round up to 13 km

If the disk is circular, the area of one circular face is 112.72 X pi = 3.990 X 104 square kilometers, to the justified number of significant digits.
The may give additional precision or may be indicators of the number of significant digits in the calculation. As an example of the latter, 5.000 kilometres is, at first sight, no different from 5 km. But, 5 km could represent any length from 4.5 to 5.5 km (rounded to the nearest integer). Whereas 5.000 km can only range from 4.995 to 5.005 km. This difference is important for error analysis.
225 mi. = 362.102 km
225 kilometers is about 738,189 feet.
To round 12.555 km to four significant figures, you would keep the first four non-zero digits, which are 12.56 km since the next digit (5) is greater than 5.
1 mile = 1.6 km 2.25 mile = 2.25 miles x 1.6 km/mile = 3.6 km
3.774 is to 4 significant figures (count them)
