Conversion Formula
The conversion from binary to decimal uses a positional notation, where each digit in the binary number is multiplied by 2 raised to its position index, starting from 0 on the right. It’s a sum of products: each binary digit times 2 to the power of its position.
For example, the binary number 10001 is interpreted as (1×2⁴) + (0×2³) + (0×2²) + (0×2¹) + (1×2⁰). Calculating each term: 16 + 0 + 0 + 0 + 1. The sum is 17 in decimal. This method works because binary is a base-2 system, where each position represents a power of 2.
Conversion Example
- Number: 1010
- Step 1: Write down binary digits with positions: 1 0 1 0
- Step 2: Assign powers of 2: (1×2³), (0×2²), (1×2¹), (0×2⁰)
- Step 3: Calculate: 8 + 0 + 2 + 0
- Step 4: Sum: 10
- Result: 1010 binary equals 10 decimal.
- Number: 1101
- Step 1: Binary digits: 1 1 0 1
- Step 2: Assign powers: (1×2³), (1×2²), (0×2¹), (1×2⁰)
- Step 3: Calculate: 8 + 4 + 0 + 1
- Step 4: Sum: 13
- Result: 1101 binary equals 13 decimal.
- Number: 11111
- Step 1: Digits: 1 1 1 1 1
- Step 2: Powers: (1×2⁴) + (1×2³) + (1×2²) + (1×2¹) + (1×2⁰)
- Step 3: Calculate: 16 + 8 + 4 + 2 + 1
- Step 4: Sum: 31
- Result: 11111 binary is 31 in decimal.
