FAQ
How does the energy converter work?
Pick a source and target unit, type a value, and the conversion applies the exact defined factor between the two units instantly.
Are the factors exact?
Yes — factors come from international definitions (for example the inch is defined as exactly 25.4 mm), so only the final display is rounded.
Can I convert in both directions?
Yes, swap the From and To selections — the same factor is simply inverted.
