Significant Figures Significant figures in the measured value of a physical quantity tell the number of digits in which we have confidence. Larger the number of significant figures obtained in a measurement, greater is the accuracy of the measurement. The reverse is also true. The number of significant figures in a result is simply the Read more about Significant Figures[…]
