When the Weight 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
The number looks wrong by about 20 percent.
You likely used 2.2 pounds per kilogram - the precise factor is 2.20462, which explains the gap.
Pounds and ounces do not add up.
There are 16 ounces in a pound - check that the ounce figure comes from the pound total times 16.
A tonne and a ton might be the same unit.
No - a tonne is 1,000 kilograms while a short ton is about 907 kilograms, so pick the right unit.
I need pounds and ounces together.
Take the whole pounds and multiply the decimal remainder by 16 for the ounces part.
My scale reads in a different unit.
Convert the reading first, then compare - mixing readings across units hides real differences.
My weight entries may be stored somewhere.
No - the conversion runs in your browser and nothing is saved.
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:
- Confusing mass with force
- Mixing tonnes with short tons
- Using an old pounds conversion
- Rounding grams too aggressively
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.
