Energy Conversion Calculator
Why does converting energy units feel like solving a riddle wrapped in an enigma? Whether you're a student crunching numbers for a physics project, a DIY enthusiast calculating energy consumption, or just someone trying to figure out how many calories are in that chocolate bar, the Energy Conversion Calculator is here to rescue you from the headache. This tool takes the guesswork out of energy conversions, letting you switch between joules, kilowatt-hours, calories, electronvolts, and BTUs with just a few clicks. No more scribbling on scraps of paper or Googling formulas—just simple, accurate, and instant results. Say goodbye to confusion and hello to clarity!
Convert energy values between different units instantly.
How It Works
This tool uses a straightforward formula to convert energy values between different units. Here's the magic behind it:
Converted Value = (Input Value × Conversion Factor of From Unit) ÷ Conversion Factor of To Unit
For example, to convert 100 joules to kilowatt-hours, the tool multiplies 100 by 1 (the conversion factor for joules) and then divides by 3,600,000 (the conversion factor for kilowatt-hours). The result? A neat 0.0000278 kWh. Easy, right?
Quick Reference Table
| Joules (J) | Kilowatt-hours (kWh) | Calories (cal) | Electronvolts (eV) | British Thermal Units (BTU) |
|---|---|---|---|---|
| 1 J | 0.000000278 kWh | 0.239 cal | 6.242e+18 eV | 0.000948 BTU |
| 100 J | 0.0000278 kWh | 23.9 cal | 6.242e+20 eV | 0.0948 BTU |
| 1000 J | 0.000278 kWh | 239 cal | 6.242e+21 eV | 0.948 BTU |
