Binary Conversion Formulas & Steps
Binary (e.g. 110010) ➔ Decimal:
Result = (1×2⁵)+(1×2⁴)+(0×2³)+(0×2²)+(1×2¹)+(0×2⁰) = 50
Result = (1×2⁵)+(1×2⁴)+(0×2³)+(0×2²)+(1×2¹)+(0×2⁰) = 50
Decimal ➔ Binary:
Divide the number by 2, record remainder, repeat with new quotient, reverse remainders at the end.
Divide the number by 2, record remainder, repeat with new quotient, reverse remainders at the end.
Binary ➔ ASCII Text:
Group bits by 8, convert each group to decimal, map to ASCII character.
Group bits by 8, convert each group to decimal, map to ASCII character.
ASCII Text ➔ Binary:
For each character: get ASCII code, convert to binary (pad to 8 bits if needed).

FAQ
| Question | Answer |
|---|---|
| How can I convert binary to decimal quickly? | Write down each bit, multiply by 2 to the position index, sum all values. |
| What’s the difference between ASCII and Unicode? | ASCII uses 7/8 bits for English; Unicode supports far more languages and symbols. |
| Can binary represent emojis or Chinese? | Yes, through Unicode encoding, as binary can represent any character or symbol. |
| Why does binary start with 0 or 1? | Binary is base-2; only digits allowed are 0 and 1. |
| Why group binary in bytes (8 bits)? | Computers process data in 8-bit blocks for efficiency and standardization. |
