You may talk about the walk to school being 12 minutes, not 12.3547937... minutes. That is because 2 significant figures is all that is needed to convey the relevant information. Furthermore, you will not have the equipment to record your time to that degree of precision.
You measure your height in [metres and] centimetres or [feet and] inches, but to no more accuracy. Your mass is measured in whole kilograms - at most 3 sig figs - not as 105.697531 kg!
Although the mathematical constant, pi, has been calculated to over 10 trillion decimal digits (as of Sept 2014), many people will use only 3 sig figs (3.14) and most of the rest will stop at 6 sig figs (3.14159).

How many significant figures should be in resulting calculation?
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
How many significant figures are used in expressing a measurement as 0.2503 L?
4 of them.
How are significant figures determined when measurements are used in calculations?
The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
What determines the number of significant figures used in reporting measured values?
The degree of accuracy of the measuring instrument.
What is a terminal decimal?
What is the difference between 6500. and 6500? The first one would be considered to have a terminal decimal. This means that instead of simply writing the number as it is, a decimal is added to the end to represent significant figures (terminal decimals are most commonly used in scientific notation). Therefore, when 6500 would only be considered as to having 2 significant figures, 6500. has 4 significant figures.
Where does similar figures used in daily life?
Construction, engineering, computers
Why are significant figures used and how are significant figures obtained?
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places

What is 12 in significant digit?
It depends upon how you got to the 12, for example: 28.6 - 16.6 = 12.0 Because each of the numbers that was used to get to the 12 had 3 significant figures, you should write the 12 with three significant figures also. However: 29 - 17 = 12 In this case, each of the numbers that was used to get to 12 had only 2 significant figures, so use only 2 significant figures in the 12.
What element is used everyday?
The roles of elements in your daily life are quite significant. For instance elements like oxygen and carbon dioxide are responsible for life itself. Other elements like nitrogen, aluminum and so on also have significant roles in our daily lives.

Where can significant figures be used for?
There are two types of significant figures, measured and exact. Numbers are often rounded to avoid reporting insignificant figures. Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement.
Solid figure used in daily life?
Just look at the house we are in,the solid figures play a key role in building the house. Look at the desk,the ball,the table,the cup,so many things in our life,they are designed by solid figures first.we can say,it is the solid figure make our life more artistical.
