Base / Radix Converter
Convert between 2/8/10/16 and any 2–36 bases, with BigInt for large numbers and grouped binary output.
—
How to use
- Type the number to convert in the "Value" box (e.g. 1010, FF).
- Choose "From base" and "To base" (any 2–36).
- Click "Convert"; the result shows grouped binary every 4 bits.
- Tip: BigInt handles arbitrarily long integers beyond the 2^53 limit.
FAQ
How large a number is supported?
BigInt is used, so any integer length is handled as long as memory allows, free of the 2^53 limit.
Why group the binary output?
Binary gets very long; grouping every 4 bits (a nibble) with spaces aids reading and manual checking.
