The least count of a measuring instrument is the smallest value that can be measured with the instrument. It determines the precision of the measurement. Significant figures, on the other hand, are the digits in a number that carry meaning about the precision of the measurement. The number of significant figures in a measurement is related to the least count of the instrument used to make that measurement.
significant figures in the original numbers used in the calculation. This means the final answer should be rounded to the same number of significant figures as the number with the least amount of significant figures.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.

To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
12.5912
Count the significant figures in each number. Calculate the minimum of these numbers. Do the multiplication Round the product to the LEAST number of significant figures, determined above.
There are [at least] four significant figures in 800600.
In 30900 there are [at least] three significant figures.
In 2080 there are [at least] three significant figures.
significant figures in the original numbers used in the calculation. This means the final answer should be rounded to the same number of significant figures as the number with the least amount of significant figures.
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The number of significant figures should be equal to the significant figures in the least precise measurement.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
