When the Angle 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 radian answer is missing pi.
A full circle is 2 pi radians, so 180 degrees equals exactly pi radians - keep the pi factor in your working.
Gradians caught me off guard.
Gradians split a circle into 400 parts, so 90 degrees equals 100 grad - the tool uses that definition.
The result does not match my calculator.
Scientific calculators switch between degree and radian mode - set yours to match the unit you enter.
Negative angles look wrong.
Negative values simply measure clockwise - the tool converts them without stripping the sign.
I need an angle over 360 degrees.
Enter it as is - the tool converts any value, including multiple turns, exactly as given.
My calculations may be saved without me knowing.
No - the conversion runs in your browser with nothing stored.
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:
- Forgetting radians use pi
- Confusing gradians with percent grade
- Entering degrees into a radian formula
- Mixing bearings with angles
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 angle units are supported?
Degrees, radians and gradians, the three standard ways to measure a turn.
How many radians are in 180 degrees?
Exactly pi radians, about 3.14159 - a full circle is 2 pi radians or 400 gradians.
What are gradians used for?
Surveying and some engineering drawing work - a right angle is 100 grad instead of 90 degrees.
Is my input stored?
No - everything runs in your browser.
