No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
The significant digits are: 3701; so there are four such digits in the measurement. These are the digits that convey the degree of precision included. Leading zeroes and trailing zeroes do not add such meaning.
Not necessarily. I measure my height to 3 sig figs (for example 178 cm), but I may choose to report is as 180 cm (to 2 sf).
false.!!!I would have to disagree with this answer!! The member did not explain themselves!! I would have to say the answer is "TRUE"!!! Any feedback on this topic? Anyone care to respond, have discussion?I am also sure that the answer is true; see the link bellow.

Significant digits do help to reflect the true precision of a measurement. This is because often the last reported digit in a measurement has an unacceptably large error associated with it. Thus, only reporting significant digits is the most conservative practice. Sometimes, however, it helps to be more accurate on a single measurement. In this case, if the measurement device is reliable to the last reported digit it may be reported for the sake of accuracy.

If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.
157.725 ml is the answer if 0.6667 is an exact measurement. If it's an actual measurement, you only have 4 significant digits of precision, and the answer is 157.7 milliliters.

Seven (7) significant figures. All digits left of the decimal to the right of any leading zeros. All digits to the right. The zero is counted because it is significant that the measurement was taken to that level of precision. The full measurement may have been 1039.5201, .5202, etc. For whatever reason, the measurement was taken to 3 digits to the right of the decimal.

Significant Digits.
It is significant to 4 digits.
