Bar length represents energy. Equal energy does not imply the same temperature, power or usefulness.
A little perspective
1 megajoule has about 2.99 times the energy of Heat one litre of water.
Measurements, assumptions & sources +
1 megajoule
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Heat one litre of water
An ideal model: 1 kg water heated by 80 K at 4,180 J/(kg·K). Excludes heat losses and phase change.
Defined examples — our methodology
The marked energy is calibrated. Unmeasured illustration details are representative.

- Comparing
- Energy ↔ Energy
- Relative size
- 1 megajoule is larger on this measurement by a factor of about 2.99. 1 megajoule's selected measurement is approximately 199% greater than Heat one litre of water's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Heat one litre of water is labelled defined energy model; treat the displayed value as a comparison anchor rather than false precision.
