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.
How vedic math is useful in daily life?
we will do maths daily in our life but for calculations it takes a lot of time so in shortcut Vedic maths was used. so it is important for us in daily life
