#️⃣ Hex to Decimal Converter
Convert between hexadecimal and decimal
💡 About Hexadecimal
Hexadecimal uses 16 symbols: digits 0-9 and letters A-F (where A=10, B=11, ..., F=15). It is widely used in programming and web design for color codes (e.g., #FF5733) and memory addresses.
Hex to Decimal Converter
This converter changes numbers between the hexadecimal (base 16) and decimal (base 10) systems. Hexadecimal uses sixteen symbols: the digits 0 to 9 plus the letters A, B, C, D, E and F, where A stands for 10 and F stands for 15. Decimal is the everyday numbering system based on ten digits. Type a value in either field and the tool returns the equivalent in the other base instantly.
Hexadecimal is widely used in computing because each hex digit maps cleanly to four binary bits, which makes long binary strings far easier to read. You will see it in memory addresses, color codes such as the familiar web color hex values, MAC addresses, and many low-level programming contexts. Converting back to decimal helps when you need a plain human-readable number.
How conversion works
To go from hex to decimal, each digit is multiplied by a power of 16 according to its position, and the results are added together. For example the hex value 2F equals 2 times 16 plus 15, which is 47 in decimal. Going the other way, the decimal number is divided repeatedly by 16 and the remainders form the hex digits. The tool handles these steps for you, so it is useful for developers, students learning number systems, and anyone working with color or address values.
