When the Number Base Converter seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
My hex digit is rejected.
Digits above nine use letters A to Z, so check that your source base actually allows that character.
The output looks completely wrong.
Confirm the source base - the tool reads what you declare, so a hex value marked as decimal will misread.
Lowercase letters fail.
Input is case insensitive, so ff and FF both parse, and the tool prints uppercase digits in the results.
Bases outside 2 to 36 are refused.
Thirty six is the limit because ten digits plus twenty six letters cover every available symbol.
I need the decimal value only.
Read the base 10 column, or copy it into our integer to hex converter for a signed hex string.
Fractional parts are cut off.
This tool converts whole numbers - round the value first if your source carries a decimal part.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Using digits the target base does not allow
- Forgetting which base the input is in
- Mixing letter case for high digits
- Assuming leading zeros change the value
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Which bases are supported?
Every base from 2 to 36, using digits 0 to 9 and letters A to Z for higher values.
Do I have to convert one base at a time?
No - enter the source base once and the tool prints the value in all supported bases together.
Can it handle large values?
Yes - typical integer ranges convert fine, though very long strings depend on your browser precision.
Is my number stored?
No - conversion happens in your browser with nothing saved.
