Hexadecimal to Decimal Converter
Hexadecimal to Decimal Converter
Enter a hexadecimal number (using digits 0-9 and letters A-F) to instantly see its decimal equivalent — useful for reading color codes, memory addresses, or other hex-encoded values.
Each hex digit represents a power of 16 read right to left, with the letters A through F standing in for the values 10 through 15 since hexadecimal needs sixteen distinct single-character digits — FF converts to 15×16 + 15×1, or 255 in decimal, which not coincidentally is also the maximum value a single byte can hold. Both uppercase and lowercase letters work identically here, since hex notation is conventionally case-insensitive across programming languages, color codes, and technical documentation alike.
- Method: each hex digit represents a power of 16, read right to left; A=10, B=11, C=12, D=13, E=14, F=15.
- Example: FF = 15×16 + 15×1 = 255.
- Case-insensitive: both uppercase (FF) and lowercase (ff) work the same way.
What is 1A in decimal?
1×16 + 10×1 = 26.
What is the decimal value of the color code FF5733?
Split into pairs: FF=255 (red), 57=87 (green), 33=51 (blue) — convert each pair separately using this tool.
