What are five significant figures?

Answer 1

Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. For example, in the number 0.00456, there are three significant figures: 4, 5, and 6. In scientific measurements, the use of significant figures helps convey the accuracy of the measurement. Therefore, understanding significant figures is crucial for proper data reporting and calculations in science and engineering.
