Base36 to Binary Converter

Summary

Enter a base-36 number (digits 0-9 and letters A-Z) and instantly get its binary equivalent.

How it works

1. Enter a base-36 number using digits 0-9 and letters A-Z (case-insensitive) into the input field.
2. Each base-36 digit is multiplied by 36 raised to its positional power and summed to get the decimal value.
3. The decimal integer is then converted to binary by successive division by 2.
4. The resulting binary string is displayed grouped in 4-bit nibbles for readability.
5. Supporting values — decimal equivalent, hex equivalent, and bit length — are shown alongside the binary output.

Use cases

• Convert base-36 encoded IDs or tokens to binary for low-level inspection.
• Cross-verify base-36 arithmetic by comparing decimal and binary representations.
• Learn how positional numeral systems work across different bases.
• Debug applications that use base-36 encoding for compact numeric identifiers.
• Explore how the same integer looks across base-2, base-10, base-16, and base-36.
• Convert short base-36 strings used in URL shorteners back to their numeric binary form.
