🔍 What is a Hex Calculator?
A Hex Calculator is a powerful digital tool that allows users to effortlessly convert hexadecimal (base-16) numbers to decimal (base-10) and vice versa. Hexadecimal is widely used in computer science, digital electronics, and programming—especially for color codes, memory addressing, and machine-level data.
This calculator eliminates manual conversion errors and saves valuable time, whether you’re a student, developer, or IT professional.
💡 How Does It Work?
A hexadecimal number uses 16 digits: 0-9 and A-F.
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
🟩 Example:
Hex to Decimal: 2A3F → 10815
Decimal to Hex: 255 → FF
With just one click, the Hex Calculator performs this conversion in milliseconds.
