That depends a lot on what exactly you are measuring. With very precise devices, time can be measured to something like 15 significant figures; in most other cases, the number of significant digits is much less - sometimes only one or two, or even less.

How many significant figure for 2.9979 x 108?
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
How many significant figures are in 8630000.000?
It only has 3 significant figures, 863.
Why when you make measurements should the answer only have the same number of significant figures as the measurement with the fewest significant figures?
This is because the uncertainty in your answer is determined by the least precise measurement. It's no use expecting your answer to be known to 4 decimal places if you are only measuring to the nearest whole mile.
Why significant figures represent the precision of a measurement and not its accuracy.?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
What is the importance of significant figures?
significant figures make data analysis less ambiguous and therefore much easier.. toindicatethe number of digits in a measurement
How many significant figures are in 66.322-13.7455?
80.0675
How many significant figures are in 250.00?
The answer is 5 significant figures. The Zeros behind the decimal count as significant figures.
How many significant figures are in 5.050mg?
4 significant figures. Zeros after the decimal are always significant.
How many significant figures does 200.00 have?
8 significant figures. The decimal makes the first 5 zeros significant while the two zeros after the decimal are significant because there is a significant figure earlier (2).
What is the rules for determing rignificant figures?
1. All non-zero digits are significant. For example, 295 has three significant figures. 2. Leading zeroes in front of a decimal are not significant. For example 0.295 has three significant figures. 3. Zeroes between other significant figures are significant. For example 2095 has four significant figures. 4. Trailing zeroes after a decimal are significant. For example 295.0 has four significant figures. And 2950 has three significant figures because the trailing zero does not occur after a decimal.
A method of expressing the accuracy of measured quantities is?
significant figures.
How many significant figures are in 60000?
There are 5 significant figures, the six plus the four zeroes. The zeroes are significant figures due to the inclusion of the decimal - with no decimal there would only be one significant figure (the six).
How many significant figures 408.03 has?
With the decimal point, all digits are counted as significant figures. Then, there are 5 significant figures for the given number.
How many significant figures does 0.44003 have?
The given decimal figure has 5 significant figures.
How many significant figures do you use for logarithms for example ln 3.02?
The number of significant figures after the decimal place matches the number of significant figures before the computation of the logarithm. Thus ln(3.02) would compute to 1.105. Three significant figures to four significant figures (3, after the decimal place).
Does 32.110 have four signifacant figures?
32.110 has five significant figures, as the last 0 is unnecessary, but is included for accuracy. Expressed with four significant figures, it is 32.11
How many significant figures are in 4.0005?
Five. If you write numbers representing the numbers in a calculation or an answer, then the number of significant figures is the number of figures written down. The number of significant figures in 351.739002 is 9; Don't confuse "significant figures" with "decimal places". The number above has 6 decimal places.
