🔢 Hex Calculator
How to Use the Hex Calculator
Our online hex calculator makes hexadecimal arithmetic effortless. Just enter two hexadecimal numbers (0‑9, A‑F) and choose an operation – addition, subtraction, multiplication, division, or bitwise AND/OR/XOR. Click Calculate to instantly see the result in hex, decimal, and binary. The tool also shows the decimal equivalents of your inputs as you type.
- Enter the first hex value in the Hexadecimal A field.
- Enter the second hex value in Hexadecimal B.
- Select the mathematical or bitwise operation from the dropdown.
- Press Calculate – the result appears immediately.
- Use Clear to reset all fields.
Invalid characters (anything other than 0‑9, a‑f, A‑F) are automatically ignored. Negative results are
displayed with a leading minus sign (e.g., -7B). Division is integer division (remainder discarded).
What Is Hexadecimal?
Hexadecimal (base‑16) is a numeral system that uses sixteen distinct symbols: 0‑9 for values zero to nine, and A‑F (or a‑f) for values ten to fifteen. It is widely used in computing and digital electronics because it represents binary values in a more human‑friendly way. Each hex digit corresponds to exactly four binary digits (a nibble), making conversions concise.
For example, the hex number 1A3F equals 1×4096 + 10×256 + 3×16 + 15 = 6719 in decimal,
and 0001 1010 0011 1111 in binary.
Common Applications
- Programming: Memory addresses, color codes (e.g., #FF5733), and debugging.
- Digital Design: Microcontrollers, FPGA configuration, and data encoding.
- Networking: MAC addresses and IPv6 addresses are often written in hex.
- Cryptography: Hash outputs and keys are frequently displayed in hexadecimal.
Frequently Asked Questions
❓ Can I use lowercase letters?
Yes, both uppercase and lowercase hex digits (a‑f) are accepted and automatically normalised.
❓ What if I type invalid characters?
The input fields filter out non‑hex characters instantly. If you leave a field empty, it’s treated as zero.
❓ Does this support bitwise operations?
Yes, you can choose AND, OR, or XOR from the dropdown. The bitwise result is shown in all three number systems.
❓ How does division work?
Division is integer division (the fractional part is truncated). Division by zero triggers an error message.
❓ Can I see the binary and decimal equivalents?
Yes, the result box always displays the decimal and binary forms alongside the hex output. You can also see the decimal value of each input below its field.
