The number of significant figures is determined by starting with the leftmost non-zero digit. The leftmost non-zero digit is sometimes called the most significant digit or the most significant figure. For example, in the number 0.004205, the '4' is the most significant figure. The left-hand '0's are not significant.... read more ›
Solution : According to the rules of significant figures `0.007 m^(2)` has one significant figures. <br> `2.64 xx 10^(24) ` kg has three significant figures.... view details ›
The quantities 0.456, 0.0456 and 0.00456 all contain 3 significant figures. In this case, you need to think in terms of exponential numbers. 0.0456 is 4.56 x 10-2 (only 3 significant figures) and 0.00456 is 4.56 x 10-3 (again, only three significant numbers). Thus, 470,000 has only 2 significant figures.... read more ›
Exact numbers, such as the number of people in a room, have an infinite number of significant figures. Exact numbers are counting up how many of something are present, they are not measurements made with instruments. Another example of this are defined numbers, such as 1 foot = 12 inches.... view details ›
The rules below can be used to determine the number of significant figures reported in a measured number. Rule 1: All nonzero digits in a measurement are significant. 237 has three significant figures. 1.897 has four significant figures.... view details ›
To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.... view details ›
If there is a decimal point, the rightmost digit is the last or least significant figure. So 0.08076 is the least significant figure.... see details ›
- All non-zero numbers ARE significant. ...
- Zeros between two non-zero digits ARE significant. ...
- Leading zeros are NOT significant. ...
- Trailing zeros to the right of the decimal ARE significant. ...
- Trailing zeros in a whole number with the decimal shown ARE significant.
Therefore, in 20.000, all zeros are significant.... continue reading ›
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.... read more ›

Why must a given measurement always be reported to the correct number of significant figures? Measurements must always be reported to the correct number of significant figures because calculated answers often depend on the number of significant figures in the values used in the calculation.... continue reading ›
For example, in the number 0.004205 the '4' is the most significant figure. The lefthand '0's are not significant. The zero between the '2' and the '5' is significant. The rightmost digit of a decimal number is the least significant digit or least significant figure.... continue reading ›
Pure Numbers: Pure numbers have infinite significant figures, meaning they are exact. If you have 12 eggs, then 12 is a pure number. You don't have 12.01 eggs, or 11.9 eggs. Physical Numbers: Physical numbers have finite significant figures.... read more ›
