Steps to Convert Binary to Decimal Numbers Manually

In this conversion process of a number from Binary to Decimal, when we convert a number with base n into a number with base 10, then each digit of the number is multiplied from the Most Significant Bit (MSB) to the Least Significant Bit (LSB) along with reducing the power of the base.

We can simply convert binary digits to decimal by performing the following steps:

  • If you want to convert a binary digit to a decimal digit, first of all, you should give power to 2, power should be started from 0 and can go up to 9 as per the given number of binary digits.
  • Now write these powers of 2 just below the binary digits starting from the left of binary digits.
  • Then multiply these results with that binary digit (0,1).
  • After getting the results, add all these products to get a decimal value of given binary digits.
  • Finally, the obtained value is the desired output.

Worked-Out Binary To Decimal CoverterExample

Example:

Convert the binary number (1001)₂ into a decimal number.

Solution:

Given binary number = (1001)₂

Now, multiplying each digit from most significant bit to least significant bit with reducing the power of the base number 2.

1 × 2³+ 0 × 2² + 0 × 2¹ + 1 × 2⁰

= 8 + 0 + 0 + 1

= 9

Thus, the equivalent decimal number for the given binary number (1001)₂ is (9)₁₀

FAQs On Free Binary to Decimal Converter Online with Steps

1. What is converting binary to decimal rules?

One of the simple methods to convert a binary number into a decimal number is using doubling. In this method, we start from the left, double your previous total and add the current digit. Then after making double the current total and add the next leftmost digit. Now repeat the further steps to get the converted output.

2. Why do we require conversion from binary number to decimal number?

The conversion from binary number to decimal number is required to read numbers that are represented as a set of 0s and 1s.

3. What is the difference between binary and decimal number systems?

The main difference between binary and decimal number systems is that the decimal number system uses ten different digits (from 0 to 9) while the binary number system uses only two different digits (0 and 1).

4. What are the similarities between binary and decimal systems?

The main similarity between binary and decimal systems is that both systems use the concept of place value. In both systems, the calculation of each digit value can be done by multiplying the digit with the matching power of 2 and 10.
