- Each position in a binary number represents a power of 2: the rightmost bit is worth 2⁰=1, the next 2¹=2, then 2²=4, and so on.
- To convert 1011₂ to decimal: 1×8 + 0×4 + 1×2 + 1×1 = 11₁₀. The tool uses BigInt to support any number of bits.

Full tool FAQ
Converting a number between bases means representing the same value using a different set of digits. A decimal (base 10) number can be expressed exactly in binary (base 2), hexadecimal (base 16), or any other base.
Frequently asked questions
Do negative numbers work?
Yes. Prefix the binary number with a minus sign.
What is the bit limit?
Up to 256 digits in the source base — enough for astronomically large numbers.
