Hex to Decimal Converter
What is Hex To Decimal?
Hex to decimal conversion is a fundamental process in computer science and digital electronics, involving the transformation of a hexadecimal (base-16) number into its decimal (base-10) equivalent. Hexadecimal numbers, which use sixteen distinct symbols (0-9 and A-F), are frequently used in computing due to their straightforward representation of binary-coded values. Converting these hex values to decimal is crucial for various applications, including programming, data processing, and network communications.
Understanding Hex To Decimal Conversion
Hexadecimal numbers, commonly known as hex numbers, are base-16 numbers. They use the digits 0 to 9 and the letters A to F (where A stands for 10, B for 11, and so forth up to F, which stands for 15). Decimal numbers, on the other hand, are base-10 numbers and use digits from 0 to 9.
To convert a hex number to a decimal number, you multiply each digit by 16 raised to the power of its position, counting from right to left, starting at 0. For example, to convert the hex number 1A3 to decimal:
- (3 * 16^0) = 3
- (A * 16^1) = 10 * 16 = 160
- (1 * 16^2) = 1 * 256 = 256
Adding these values together: 3 + 160 + 256 = 419. Therefore, the hexadecimal number 1A3 is equal to 419 in decimal.
Usage in Different Industries
Computing
Hexadecimal is extensively used in computer science because it offers a more human-readable form of binary-coded values. For example, memory addresses and color codes in web development are often represented in hex.
