Conversion Formula
The conversion from hexadecimal to decimal involves multiplying each digit by 16 raised to the position power, counting from right to left starting at zero. For example, to convert 28 hex: 2 × 16^1 + 8 × 16^0 = 32 + 8 = 40. This method works because hexadecimal digits are base-16, and each position signifies a power of 16.
Conversion Example
- Number: 3A (hexadecimal)
- Step 1: Identify digits: 3 and A (which equals 10 in decimal)
- Step 2: Calculate: (3 × 16^1) + (10 × 16^0) = (3 × 16) + (10 × 1) = 48 + 10 = 58
- Result: 3A in hex equals 58 in decimal.
- Number: 1F (hexadecimal)
- Step 1: Digits are 1 and F (15 in decimal)
- Step 2: Calculate: (1 × 16^1) + (15 × 16^0) = 16 + 15 = 31
- Result: 1F in hex equals 31 in decimal.
- Number: B4 (hexadecimal)
- Step 1: Digits B and 4, B equals 11
- Step 2: Calculate: (11 × 16^1) + (4 × 16^0) = 176 + 4 = 180
- Result: B4 in hex equals 180 in decimal.
