Remember that digits of a number are not said to be as significant if they do not add information regarding the precision of that number. They include:

• Leading zeros as in 0.007 or 0065

• Trailing zeros as in 65000 when no decimal point is present. If an over-line is present as in 65000, the over-lined zero is said to be as significant, but the trailing zeros are not as significant

You can unfold the question of how to find significant figures with the ease of our simple significant digit calculator.

Well, here are some significant figures rules that you must know before you go!

1. Remember that every digit that is not zero is significant

**For Example:**

• 2.547 includes four sig figs

• 427 includes three sig figs

2. When zeros are between digits that are not zeros are said to be significant

**For Example:**

• 800091 includes six sig figs

• 2091 includes four sig figs

3. If a zero is to the left of the first digit that is not zero, then it is not said to be as significant

**For Example:**

• 0.005555 includes four sig figs

• 0.00076 includes two sig figs

4. Trailing zeros – means the zeros which right after the final non-zero digit are said to be significant if the number consists of a decimal point

**For Example:**

• 7.000 includes four sig figs

• 900. includes three sig figs

• 0.070 includes two sig figs

5. If the number does not have a decimal point, then trail zeros are not said to be as significant

**For Example:**

• 700 or 7 × 10^2 only includes one significant figure

• 71000 includes two sig figs

6. Remember that the number of sig digits in exact numbers is infinite – this is also true for the numbers that are defined

**For Example:**

• 1 meter = 1.0 meters = 1.000 meters = 1.00000000 meters

Thankfully, you come to know the simple sig figs rules, utilize the above sig figs calculator to know how many sig figs are in the numbers that you mentioned!

The outcome of either addition/subtraction must have the same number of decimal places similar to the least number of decimal places in any number involved.

**For Example:**

100 (includes 2 sig figs) + 32.643 (includes 5 sig figs) = 132.643, which should be rounded to 133 (includes 3 sig figs)

The outcome of either multiplication or division should have as many sig figs as the number involved that contains the least number of sig figs.

**For Example:**

3.0 (includes 2 sig figs) 14.60 (includes 4 sig figs) = 43.8000 which should be rounded off to 44 (includes 2 sig figs)

• If the digit to be dropped is > (greater than) 5, then the last retained digit in increase by one.

**For Example:**

13.6 is rounded to 14

• If the digit to be dropped is < (less than) 5, then the last remaining digit is left as it is.

**For Example:**

14.4 is round to 14

• If the digit to be dropped is = (equal to) 5, and if any digit that following it is not 0, then the last remaining digit is increased by one.

**For Example:**

13.51 is rounded to 14

• If the digit to be dropped is = (equal to) 5, and followed only by zeros, then the last remaining digit is increased by one if the digit is odd, but left as it is if the digit is even.

**For Example:**

11.5 is rounded to 12, and if there is 12.5, then it is rounded to 12

Furthermore, get the ease of sig figs calculations using our simple significant number calculator.

Rules for Numbers WITHOUT a Decimal Point:

- You have to start counting for sig-figs ‘On the First non-zero digit.’
- Then, start counting for sig-figs ‘On the Last non-zero digit.’
- Remember that the non-zero digits are always said to be as significant
- And, zeroes in between two non-zero digits are said to be as a significant and all other zeroes are in-significant

Rules for Numbers WITH a Decimal Point:

- There is a need to start counting for the sig. figs ‘On the First non-zero digit.’
- Then, Stop Counting for the sig. figs ‘On the very Last digit, regardless it doesn’t matter whether the last digit is a zero or non-zero number.’
- The non-zero digits always indicate significant
- And, any zero after the first non-zero digit is still said to be as significant. Any zero before the first non-zero digit are said to be as in-significant

Mathematically, 3.0, 3.00, and 3.000 are all the same value, but 3.000 show that it has been measured with the more precise instrument. By sig-figs rules, the zeroes in all three numbers are represented ‘significant figures.’ Thus, 30.0 have three sig -figs.

According to mathematical number, 100 (or any other number) is an exact quantity on which the concept of significant figs doesn’t apply. If you want to measure 100 with 3 sig figures (implying uncertainty of), then you could write it as ‘100.’ However, you can put the value into the above sig fig calculator with uncertainty to get instant result.

In the expression of 0.001, 1 is said to be as significant fig, hence 0.001 has only 1 sig. fig. By sig rules, any trailing zero before the decimal point does not count. For example, 1000, 100, 10 all have only 1 sig fig. E:g – 101 have 3 and 1001 have 4 significant figs respectively.

Keep in mind, all non-zeroes digit is said to be as significant. (2.3, 22, and even 120 all have 2 significant figs) and any zero between non-zero digits are significant (203 and 1.02 have 3 sig-figures).
