Sig Fig Calculator


The sig fig calculator helped to convert the number into the desired amount of significant figures and represented as a new number. This calculator also helps to solve the expression of significant figures. Sig figs help to maintain the consistency level in the calculation as it provides precision in the calculation. Significant figures provide a precise and accurate value of the significant digits.

Based on the systematic observation, significant figures provide an accurate answer and maintain the consistency level. In measure amount of precision shown by the significant figures.

What are the significant figures?

Significant figures help to add the value in the calculation and provide a precise value of the whole number. Avoiding the repeating number in any observation, the numbers rounded and provide a precise result to consider. However, when rounding off the number don't lose the precision as if you round off the measurement of any particular observation; the original observation may be rounded off. Use rounding calculator to avoid such problems.

What are the significant rules?

To gather which are the significant figures and which are not, different rules are here to gather the appropriate answer.

  1. If the decimal value zero on the left side is less than 1, considered as non-significant, for example, 000.097 contains six significant figures and considered as non-significant.
  2. Between two considerable number, any zero considered as Significant. For example, the number 2.09 contains three significant figures, and 6.809 contains four significant figures.
  3. Zero after the figure and decimal number considered as significant. For example, 0.340 contains four significant figures and are label as significant figures.   
  4. In scientific notation, exponential digits are not significant. For example, 1.45x10^16 considered as non-significant. 
  5. Non zero digits taken as significant.  For instance, the number 5.467 contains 4 significant figures, and 4.23 contains three significant figures.   
  6. Using different unit ambiguity can be avoided. Using scientific notation, ambiguity can be avoided effectively.

Significant figures help to provide a significant amount and reflect the accuracy of the measurement in precise form.

How to use our sig fig calculator?

This sig fig calculator works in two different modes, one is to round off the number and the other one is by performing arithmetic operations on different numbers, for example, 7.9/6.78.  

Significant figures can be calculated manually or by using our online sig fig calculator above. It provides the desired number of significant decimal numbers.

Suppose we have a numeric figure 0.007667 and we want two decimal numbers. Trailing numbers are not counted, and we get 0.0076. 

Another example if we don't have the decimal number 4,786,987 and we want 4 significant figures. Rounding off the number well gather 4,786,000. If the number is in the Scientific notation, then we'll apply the rules.

In the estimation dealing with the numbers, the number should not be higher than the log base power 10.

Significant figures in Operation:

Apart from the above mention rules, there are some additional rules as well.

  1. With the least number, the result of the operation can't be more significant. For example, the number are sorted as 11.02 + 13.65 + 17.89 = 42.56 = 43. The conclusive results are two significant figures. 
  2. If subtraction and addition calculations are performing, then all the calculations should be performed one time, and then significant rules should be applied to get a precise result.  
  3. For the division and multiplication results, the calculation should be applied once, and significant rules should be applied after the division or multiplication. 
  4. If the mixed calculations performed that contains all the subtraction, addition, and multiplication process, then the calculation should be sorted first before applying the significant rules. The multiplication of the numbers performed first, then numbers are rounded off and the new process performed.
