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.
Temperatures are typically measured with 1-2 significant figures, as precision beyond that is usually not needed for everyday purposes. However, in scientific contexts, temperatures can be measured with more significant figures depending on the sensitivity of the measuring instrument.
For doing significant figure you down count from the start the required amount, so 645533 would become 646000.
A meteorite that contains a significant amount of iron.
No, pilot lights do not use a significant amount of gas. They are designed to consume a small, steady amount of gas to keep the flame lit, but the overall consumption is minimal compared to other gas appliances.

you must know the correct amount of significant figures to round to because it will allow you to eliminate "insignificant" figures, which will shorten things up a bit when recording scientific information involving such figures.
Which ever number has the least significant figures is the amount you use. For example: 4.123/2.2=1.874 But the correct answer with significant figures is 1.9
To find a number to two significant figures or any amount of significant figures you look at one plus the amount of asked figures, in this case the third significant figure, and if it is 5 or greater increase the asked amount of significant figures by one. If it is 4 or less make no changes to your number. Finally report the calculated number with the asked amount of significant figures.
1.0947. This can be nicely rounded up to 1.1 as it is reasonably close.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
28.26 times pi which is 3.14 equals 88.78 or 88.8 if you need the correct amount of significant figures.
No, the one with the least.
4 of them.
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)
The number -2.006 should be reported with four significant figures. This is because all non-zero digits in the number are considered significant, and the zeros between the decimal point and the non-zero digit are also significant.
When multiplying, the product is going to have the same number of significant digits as the least amount in the factors. So 8.08 has three significant digits and 5.232 has four significant digits. Remember that any zeros in-between significant digits is always significant. Because the least amount of sig digs in the factors is three (from 8.08), the product is going to have three sig digs.Multiplying out normally: 8.08 × 5.232 = 42.27456Rounded to three places: 42.3
