Question

What do you understand by significant figures?

Answer 1

Answer:

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.

Answer 2

Significant figures are any non-zero digits or trapped zeros. They do not include leading or trailing zeros. When going between decimal and scientific notation, maintain the same number of significant figures.
