It is the expression of accuracy of a physical quantity. The value in digits, accurately known in a measurement plus one digit that is not certain, is called significant figures. Significant figures is directly proportional to the accuracy of measuremen..

The reliability of a measurement is indicated by the number of digits used to represent it. To express it more accurately we express it with digits that are known with certainty. These are called as Significant figures. They contain all the certain digits plus one doubtful digit..

The reliability of a measurement is indicated by the number of digits used to represent it. To express it more accurately we express it with digits that are known with certainty. These are called as Significant figures. They contain all the certain digits plus one doubtful..

The significant figures are all those digits which we are absolutely sure of plus those digits that we are not sure of. However, the digits have a meaningful value. This also provides us with information about the extent of uncertainty in measurement. E.g., All the experiment..

Problems - Significant Figures - 1. State the number of significant figures in each of the following: (i) 208.91 (ii) 0.00456 (iii) 453 (iv) 2.945 x 10 4 (v) 0.3..

The accuracy of a result is taken to be equal to the least accurate among the numbers, when 2 or more numbers are used to add, subtract, multiply or divide. The number of significant figures in the result, is equal to the number of significant digits in the least..
