What is an example for significant figures?

Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)


What is the product of the number 1000 and the measurement 0.003 57 m expressed in the correct number of significant digits?

The product of 1000 and 0.00357 is 3.57. The result should have three significant figures as that is the lowest number of significant figures given in the original numbers being multiplied.

How does conversion factors affect the number of significant figures in a problem?

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.
