The significant figures (also called significant digits) of a number are those digits that carry meaning contributing to it's precision. This includes all digits except:
- Leading zeros where they serve merely as placeholders indicate the scale of the number.
- spurious digits introduced, for example, by calculations carried out to greater accuracy than that of the original data, or measurements reported to a greater precision than the equipment supports.

The number of significant figures in a measured quantity is determined by counting all the certain digits, plus the first uncertain digit. Trailing zeros after a decimal point are considered significant, but leading zeros are not. Uncertainty in the last digit increases the level of precision and hence the number of significant figures.

When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?
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.
Determine the number of significant figures of 2603000?
There are four significant figures in the number 2603000. Zeros at the end of a number are considered significant if they are to the right of the decimal point or if they are after a non-zero digit.
How do you tell what was the most significant figures?
Significant figures in a number are all the non-zero digits and zeros between them that are significant for the precision of the measurement. To determine the significant figures in a number, count all the non-zero digits and any zeros between them. Trailing zeros after a decimal point are also significant figures.
Determine the number of significant figures in each measurement 12.90 s?
4 significant figures.Zeros are significant if they are between two non-zero numbers, or if they are "trailing" zeros in a number with a decimal point.Eg.0.000047 = 2 significant figures4.7000 = 5 significant figures
A measure of the quantity of matter is?
The measure of the quantity of matter is mass. Mass is a fundamental property of an object that determines its resistance to acceleration. It is typically measured in units such as kilograms or grams.
When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?
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.
What is the number of measured quantity 351g?
The number of the measured quantity is 351 grams.
What is the quantity in unit rates?
The quantity in unit rates refers to the amount or number being measured or compared in relation to a single unit of another quantity. It helps to determine the rate at which the original quantity is changing or occurring.
Is ml a measured number or an exact number?
Milliliters (abbreviated "ml") is generally a measured quantity.
Why are significant figures used and how are significant figures obtained?
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
What is the meaning of the number of digits reported in a measured quantity?
the number of digits reflects the certainty in the measurement
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
How many significant does 0.00000006 have?
"Dose" is a measured portion of a medicine. I am not aware of any number - no matter how small, that has measured quantities of medication - wther or not that dose is significant!
What is the number of significant figures in 546 km?
3 of them.
What are the similarities between pressure and quantity?
Pressure is a force measured in amounts. Quantity is about amounts of something. Therefore they are similar by virtue of being about a `number of things'.
What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How do you determine how many significant figures to keep in an answer obtained by adding and subtracting?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
