If you have written a number such as 111.1 to 3 significant figures, for example, (which would be 111) then we would write "111 (to 3 s.f.)".
3 significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
4, assuming the 0 at the end is to indicate the degree of precision.
There are 2 significant figures in this number.
3.774 is to 4 significant figures (count them)
The number 0.00038 has two significant figures. Significant figures are digits that carry meaning contributing to the precision of a number. In this case, the zeros before the 3 and 8 are not considered significant because they are leading zeros that simply indicate the decimal's placement. The 3 and 8 are the significant figures in this number.
There are only one significant figure in the number 20000. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, the zeros in 20000 are not considered significant because they are serving as placeholders to indicate the magnitude of the number rather than its precision.
The number 20.0 has three significant figures. The zeros at the end of the number after the decimal point are considered significant because they are placeholders to indicate the precision of the measurement. Therefore, all digits in 20.0 are significant.
When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.
The number 14500 has five significant figures. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, all the digits in 14500 are considered significant because they are all non-zero and are part of the measurement.
Three significant figures are in this number.
3 significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
642000 expressed as four significant figures is 6.420e5
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are six significant figures in this number (i.e. all the figures here are significant).
