The Significant figures calculator

Here’s to another science tool that makes your life less complicated with solutions, of course. Today’s new calculator (calc) is, “The Significant figure calculator”, also known as “Sig Figs”. This calculator is a tool that can convert any number into a brand new one. Also, solves the illustrations with the appropriate sig figs. Let’s explore the article for more information about this calc.

The sig figs are those digits that are supposed to add meaning to the entire value of the numbers. The rounding off numbers must get done when there is a repetition of the non-significant figures. One must be precise in doing so. Now, let us tell you more about them in detail.

What are the sig fig calculator rules?

The sig figs calc rules below suggest that whether the digits are considered as significant or not. They are:

  • All the zeroes that are present at the decimal portion before the significant figures are NOT significant. For example: 0.0008 or 0.00876
  • All the non-zero digits are significant. For example 4.18 or 2.43
  • Zeroes that are present between any two sig figs are significant. For example 4.204 or 1.62005
  • All the final zeroes and the trailing ones ONLY at the decimal point are significant. For example, 1.500 or 2.632000
  • Zeroes that occurred at the end of a digit are NOT significant. For example: 433,000

How to use the significant digits calculator?

Keeping the above rules in mind, now we learn how to use the sig fig calculator. The guidelines will get mentioned below:

  • There are two modes in which the calculator works: a) It executes arithmetic algebraic operations on many digits; b) It rounds off the number to your desired results.
  • We can also calculate the result by hand or by the calculators. Remembering the above-listed points, let us take an example, 0.004562 to 2 significant digits. Now, as we know trailing zeroes are placeholders so, we don’t consider them.
  • Then, take up the sig fig, 4562 to 2 digits and the answer would be 0.0046.
  • Now, let us take another example, which doesn’t have decimal values. Like 4, 32,567 to 4 digits and so we round the whole figure to the nearest thousand. The answer is 4, 33,000
  • Another point that comes up, if it is a scientific notation to deal with. To use these equations in the significant digit calculator, use E notation, this converts x10 into the lower or the upper letter case, “e”. For example, 5.063x10^23 is similar to 5.063E23 or 5.063e23. Also, for a small number like 9.16x10^-17 then its E is equivalent to 9.16E-17 or 9.16e-17
  • Also, remember when you have to deal with estimating digits, the significant figure shouldn’t get bigger than log base 10 and then round it off to the nearest possible integer. For example, if your sample’s size is 150 and also, the log of 150 is equal to 2.18, so we use 2 significant digits.

How many sig-figs calc and operations?

The operations of these arithmetic problems have considerable processes and methods. Also, to top it, we have the primary methodology to solve them like addition, subtraction, multiplication, and division. The following would be some of the major points that you must remember while operating on the problems. They are:

1. Addition and Subtraction:

  • While you perform operations with the help of addition and subtraction, you must remember that the result you’ll obtain should not have more decimal places than the number that has the least precision.
  • For example, 128.1+1.72+0.457 and in this problem, you have 128.1 as the number with the least accuracy. So, using the sig fig addition calculator, the operation would result in 128.1+1.72+0.457=130.277, which rounds off to have 130.3
  • Solve the problem with the essential addition and subtraction methodology then apply the rules of sig figs on the final result.

2. Multiplication and division

Here, we would solve the arithmetic problems by dividing and multiplying significant figures.

  • While you perform multiplication and division on the arithmetic problem, make sure that the desired result should have no more critical data than the number that least has them.
  • For example, 4.321*3.14 and in this operation, you have 3.14 as a number who has the least amount of sig figs. So, their result is 4.321*3.14=13.56974, which rounds off to 13.6.
  • Again make sure you do the basic multiplication and division at the beginning of the operation and apply the rules of the significant figures at the final result. You can apply a similar method for division by using dividing significant figures calc.

3. Mixed operations:

  • Now, if you would mix these operations like addition/subtraction to multiplication/division, then make sure you count the number of significant figures with each step and remember the central equation.
  • For example, 12.13+1.72*3.4 and now by basic methodology, we have 12.13+5.848, which you got after applying the multiplication first. Then, remember that the central equation’s result should get 2 significant figures with one decimal place. Now, as we know that sig fig rules should get applied in the result. So, by using adding significant figures calculator, the operation would result in 12.13+5.848=17.978, which rounds off to have 18.0
  • Real numbers or conversion factors cannot disturb the accuracy of the calculations. Instead, they could get considered as they have an infinite number of sig figs. For example, let’s consider speed conversion, where you multiply the m/s value to 3.6 to obtain the result in km/hr. Like 15.23 m /s and so to convert it in km/hr you must multiply it by 3.6, but with increasing sig fig calculator, it can’t happen. The result would still appear in m/s. To obtain value in the calc then you must enter the values like 15.23*3.600
