Understanding Number Systems
Computers run on binary (0s and 1s). This calculator helps you translate human numbers (Decimal) into computer language.
- Decimal (Base 10): Our standard 0-9 system used in daily life.
- Binary (Base 2): Uses only 0 and 1. Each digit is called a "bit". This is how computers store data.
- Hexadecimal (Base 16): Uses 0-9 and A-F. It's a shortcut way to write Binary. (e.g., Binary
1111is just HexF).
