Significant figures, often referred to as sig figs or significant digits, are a fundamental concept in mathematics and science. They help us express the precision of measurements and calculations. Whether you’re a student, scientist, or just curious about the number of significant figures in a value, the “Significant Figures Calculator” can assist you in determining this crucial information.
What Are Significant Figures?
Significant figures are the digits in a number that contribute to its precision. They include all non-zero digits, any zeros between significant digits, and any trailing zeros in the decimal portion of a number. For example:
- In the number 125634, there are six significant figures: 1, 2, 5, 6, 3, and 4.
- In 0.00520, there are three significant figures: 5, 2, and 0.
Significant figures allow us to convey the degree of certainty in a measurement or calculation. The more significant figures, the more precise the value.
