When the Power 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 horsepower figure differs from the brochure.
Electrical and mechanical horsepower differ slightly - the tool uses the mechanical standard of 745.7 watts per hp.
The appliance number seems tiny.
Watts measure rate - multiply by hours used to get energy, then compare with kilowatt-hour bills.
BTU per hour does not match my heater.
One watt equals about 3.412 BTU per hour - check whether the rating is input or output heat.
Peak and running power got mixed up.
Convert the continuous rating for real-world sizing - peak numbers only last for short bursts.
Large generator figures look cluttered.
Read the kilowatt column - the tool prints every unit so the scale stays clear.
My ratings may be stored on a server.
No - the conversion runs in your browser with nothing 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 power with total energy
- Using electrical instead of mechanical hp
- Forgetting the 745.7 watt definition
- Mixing continuous and peak ratings
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 power units are supported?
Watts, kilowatts, mechanical horsepower and BTU per hour for electrical, mechanical and heating power.
How many watts are in a horsepower?
About 745.7 watts for mechanical horsepower - electrical hp is slightly lower at 746 watts.
How do I convert watts to BTU per hour?
Multiply by 3.412 - so a 1,000 watt heater produces about 3,412 BTU per hour of heat output.
Is my input stored?
No - everything runs in your browser.
