5.Binary to Decimal Conversion Examples?

Converting binary numbers to decimal is a simple process that involves understanding the place value of each digit in a binary number. In the binary system, each digit (bit) represents an increasing power of 2, starting with the rightmost digit. Let's go through a few examples to explain this:

Example 1: Converting 1011 from Binary to Decimal

Step 1: Write the binary number and assign powers of 2 to each digit, starting with 0 on the right.

- 1 (2^3), 0 (2^2), 1 (2^1), 1 (2^0)

Step 2: Calculate the value of each digit.

- 1 × 2^3 = 1 × 8 = 8

- 0 × 2^2 = 0 × 4 = 0

- 1 × 2^1 = 1 × 2 = 2

- 1 × 2^0 = 1 × 1 = 1

Step 3: Collect the values.

- 8 + 0 + 2 + 1 = 11

So 1011 in binary is equal to 11 in decimal system.

Example 2: Converting 110010 from Binary to Decimal

Step 1: Assign a power of 2 to each digit, starting from the right.

- 1 (2^5), 1 (2^4), 0 (2^3), 0 (2^2), 1 (2^1), 0 (2^0)

Step 2: Calculate the value of each digit.

- 1 × 2^5 = 1 × 32 = 32

- 1 × 2^4 = 1 × 16 = 16

- 0 × 2^3 = 0 × 8 = 0

- 0 × 2^2 = 0 × 4 = 0

- 1 × 2^1 = 1 × 2 = 2

- 0 × 2^0 = 0 × 1 = 0

Step 3: Collect the values.

- 32 + 16 + 0 + 0 + 2 + 0 = 50

So 110010 in binary is equal to 50 in decimal system.
