Because the extra digits are just clutter suggesting a spurious level of accuracy.

How do you use significant digits in a sentence?

The number 202.45 has five significant digits.


Why do you use significant digits when dealing with measurements?

Measurements need to be specific so we use significant digits.


What digits are considered significant in a measurement?

Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits. Zeros are sometimes significant and sometimes aren't: # Zeroes placed before other digits are not significant; 0.0968 has three significant digits. # Zeroes placed between other digits are always significant; 70063 kg has five significant digits. # Zeroes placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. # Zeroes at the end of a number are significant only if they are behind a decimal point as in (c). Otherwise, it is impossible to tell if they are significant. For example, in the number 8200, it is not clear if the zeroes are significant or not. The number of significant digits in 8200 is at least two, but could be three or four. To avoid uncertainty, use scientific notation to place significant zeroes behind a decimal point: 8.200 * 103 has four significant digits 8.20 * 103 has three significant digits 8.2 * 103 has two significant digits


How does the precision of a calculated answer compare to the precision of the measurements use to obtain it?

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


What is 35164 to 3 significant figure?

35164 is 35200 rounded to 3 significant figures. To round to 3 sig fig, use the 4th digit to decide whether to round up or down; digits after the first 3 are replaced by zeros: 4th digit is 6, so round up 35164 → 35200 to 3 sig fig.
