What is Decimal to Hexadecimal Conversion?

Decimal to hexadecimal conversion transforms base-10 numbers into base-16 numbers. Hexadecimal uses digits 0-9 and letters A-F.

Why Use Hexadecimal?

Hexadecimal is extensively used in computing for compact representation of binary data:

Common Use Cases:

  • Color codes in web design (#FF5733)
  • Memory addresses in programming
  • MAC addresses and IPv6 addresses
  • Cryptography and hash values
  • Assembly language and debugging

How Does It Work?

Decimal to hexadecimal conversion involves repeatedly dividing by 16 and using remainders (0-9, A-F) in reverse order.

Examples:

  • Decimal 255 becomes Hexadecimal FF
  • Decimal 16 becomes Hexadecimal 10
  • Decimal 4095 becomes Hexadecimal FFF

Understanding Hexadecimal

Each position represents a power of 16:

  • Position 0: 16^0 = 1
  • Position 1: 16^1 = 16
  • Position 2: 16^2 = 256
  • Position 3: 16^3 = 4096

Digits A-F represent decimal values 10-15.

Color Codes Example

Web colors use hexadecimal:

  • #FF0000 is pure red (255, 0, 0)
  • #00FF00 is pure green (0, 255, 0)
  • #0000FF is pure blue (0, 0, 255)
