When the Energy 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 kWh figure seems huge next to joules.
One kWh equals 3.6 million joules - that scale jump is real, not an error.
My calories look wrong for food labels.
Food Calories are kilocalories - one nutritional Calorie equals 4,184 joules, a thousand times the small calorie.
BTU does not match my boiler spec.
The tool uses the IT BTU of about 1,055.06 joules - some tables quote thermochemical BTU, which differs slightly.
I mixed up watts and watt-hours.
Watts measure rate while watt-hours measure energy - multiply the power by hours worked to get the energy figure.
Very large numbers are hard to read.
Switch to kilowatt-hours or BTU for big values - the tool shows every unit at once.
My energy figures may be saved on a server.
No - the calculation runs in your browser and nothing is 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:
- Confusing power with energy
- Mixing kilojoules with joules
- Using nutritional Calories unaware
- Assuming BTU has one single definition
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 energy units are supported?
Joules, kilowatt-hours, calories and BTU for electrical, mechanical and heating energy.
How many joules are in a kilowatt-hour?
Exactly 3,600,000 joules - one kilowatt sustained for one hour.
What is the difference between calories and Calories?
A lowercase calorie is 4.184 joules, while food Calories are kilocalories of 4,184 joules.
Is my input stored?
No - everything runs in your browser.
