Theoretical total mass–energy of 1 gram of matter (25 GW·h) [177] 10 14 1.8×10 14 J Energy released by annihilation of 1 gram of antimatter and matter (50 GW·h) 3.75×10 14 J: Total energy released by the Chelyabinsk meteor. [178] 6×10 14 J: Energy released by an average hurricane in 1 second [179] 10 15: peta-(PJ) > 10 15 J
The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. [1] [2] The rise of easy popularization of ideas through the internet has greatly increased the relevant examples, but the asymmetry principle itself has long been recognized. [3]
However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes.
weather: Hurricane Katrina's rate of release of latent heat energy into the air. [48] 3 × 10 14: tech: power reached by the extremely high-power Hercules laser from the University of Michigan. [citation needed] 4.6 × 10 14: geo: estimated rate of net global heating, evaluated as Earth's energy imbalance, from 2005 to 2019.
The energy required to lift an apple up 1 m, assuming the apple has a mass of 101.97 g. The heat required to raise the temperature of 0.239 g of water from 0 °C to 1 °C. [15] The kinetic energy of a 50 kg human moving very slowly (0.2 m/s or 0.72 km/h). The kinetic energy of a 56 g tennis ball moving at 6 m/s (22 km/h). [16] The food energy ...
The enthalpy of fusion is the amount of energy required to convert one mole of solid into liquid. For example, when melting 1 kg of ice (at 0 °C under a wide range of pressures), 333.55 kJ of energy is absorbed with no temperature change. The heat of solidification (when a substance changes from liquid to solid) is equal and opposite.

The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
