Hex to Binary converter
What is a Hexadecimal Number?
A hexadecimal number, often abbreviated as "hex," is a number system with a base of 16. Unlike the decimal system (base-10), which uses the digits 0-9, hexadecimal uses the following 16 symbols:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
- 0-9 represent the decimal values 0 to 9.
- A-F represent the decimal values 10 to 15.
Hexadecimal is widely used in computing and digital systems because it is more compact than binary (base-2) and easier for humans to read and write. It is commonly used to represent memory addresses, colors in web design, and binary data.
Example:
- The hexadecimal number 1A3F can be converted to decimal as follows:
1 × 16³ + 10 × 16² + 3 × 16¹ + 15 × 16⁰ = 6703 in decimal.
What is a Binary Number?
A binary number is a number expressed in the base-2 numeral system, which uses only two symbols: 0 and 1. Each digit in a binary number is referred to as a bit. Binary numbers are the foundation of digital systems and computing because they align directly with the on/off states of transistors in electronic devices.
In the binary system:
- 0 represents the "off" state.
- 1 represents the "on" state.
Binary numbers are used in various applications, including arithmetic operations in computers, data storage, and network protocols.
Example:
- The binary number 1011 can be converted to decimal as follows:
1 × 2³ + 0 × 2² + 1 × 2¹ + 1 × 2⁰ = 8 + 0 + 2 + 1 = 11
How to Convert Hexadecimal to Binary?
Converting a hexadecimal (hex) number to binary is a straightforward process because each hex digit corresponds to exactly 4 binary digits (bits). This is due to the fact that the base-16 system (hex) can represent 16 values, which aligns perfectly with the 16 combinations of 4 binary bits (2⁴ = 16).
Steps for Conversion:
- Write the Hex Number: Start with the hexadecimal number you want to convert.
- Replace Each Hex Digit: Convert each hex digit into its 4-bit binary equivalent using a conversion table.
- Combine the Binary Groups: Write down all the binary groups in the same order as the hex digits to form the full binary number.
Hex to Binary Conversion Table:
Hex Digit | Binary Equivalent |
---|---|
0 | 0000 |
1 | 0001 |
2 | 0010 |
3 | 0011 |
4 | 0100 |
5 | 0101 |

Example Conversion:
Convert the hex number 2F3 to binary:
- Write each hex digit:
- 2 → 0010
- F → 1111
- 3 → 0011
- Combine the binary groups:2F3 (hex) = 0010 1111 0011 (binary)
