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.)".
The number 805 has three 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)
142.617 has 6 significant figures and should not be confused with the number of decimal places to which the number is given which is 3dp. To 5 significant figures, the answer is 142.62 To 4 significant figures, the answer is 142.6 To 3 significant figures, the answer is 142 To 2 significant figures, the answer is 140 (the final zero is retained to indicate the position of the decimal point which , if shown, would be 140.0 To 1 significant figure, the answer is 100
Three significant figures are in this number.
The number 805 has three 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
There are two significant figures: 2 and 0 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 2) are not significant.
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).
There are 3 significant figures in this number.
4, assuming the 0 at the end is to indicate the degree of precision.
There are 4 significant figures in this number.
