Heat is energy that is transferred between objects at different temperatures; it flows from a high to a low temperature. Chemical and physical processes can absorb heat (endothermic) or release heat (exothermic). The SI unit of energy, heat, and work is the joule (J). Specific heat and heat capacity are measures of the energy needed to change the temperature of a substance or object.

It provides equivalences between units, such as the conversion of 1 Mg/m³ to 1 gm/cm³ and of 1 J to calories and Btu. The page also lists fundamental physical constants like the Boltzmann constant, gas constant, Avogadro constant, and gravitational acceleration.
