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.

BeauThe 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.
