Sig Fig Rules

[006033476]

If tailing zeros in sig figs are not significant, why are leading zeros and zeros between nonzero digits significant?

Leading zeroes are not considered significant. Zeroes between nonzero digits serve a greater role than just a placeholder, which is why they are significant.

[Hannah Kim 3E]

Leading zeros indicate the level of precision or accuracy in a number, "0.76" is different from "0.076". Zeros between nonzero digits convey the number of meaningful digits, "706" are all significant.

[Isabelle Huerta 2I]

Leading Zeros are used to indicate the scale or magnitude of a number but don't add to the precision of the measurement. Zeros between nonzero digits are considered significant because they indicate precision or accuracy in the measurement. Tailing zeros in a number without a decimal point may or may not be significant. The significance of zeros in significant figures is determined by their position in the number and their role in indicating precision or uncertainty in the measurement.
