The Significant Figures Calculator is a precise tool designed to identify and compute using significant figures. Significant figures are the digits in a number that contribute to its precision, excluding any leading zeros. This concept is pivotal in science and engineering to reflect the accuracy of measurements and calculations.

**Chemistry:**Reporting experimental results or concentrations.**Physics:**Representing measurements or constants.**Engineering:**Designing systems with specific tolerances.**Astronomy:**Detailing vast cosmic distances or sizes.

Users input a number, and the calculator identifies its significant figures. For example, for the number 0.00456, the significant figures would be 456. Additionally, it can perform arithmetic while preserving the correct number of significant figures.

In disciplines demanding accuracy and precision, understanding significant figures is essential. The Significant Figures Calculator aids in achieving this precision, ensuring data integrity and consistency.
