Watts (W) to Gigawatts (GW) Conversion
Watts
The watt (W) is the SI derived unit of power, defined as one joule per second (J/s = kg·m²·s⁻³), representing the rate of energy transfer or conversion. Named after Scottish engineer James Watt, whose steam engine improvements launched the Industrial Revolution, the watt is the coherent unit for all forms of power — mechanical, electrical, thermal, and acoustic. A human at rest produces about 80 W of thermal power; a professional cyclist sustains approximately 400 W during a race; a lightning bolt peaks at around 10¹² W for microseconds.
Gigawatts
The gigawatt (GW) is a unit of power equal to exactly 1,000,000,000 watts (10⁹ W), the scale of national electrical grids and large-scale power generation. The total installed electricity generation capacity of France is approximately 130 GW; that of the United States exceeds 1,100 GW. A lightning bolt peaks at around 1 TW for microseconds. The rapid growth of solar and wind power is often described in gigawatts of installed capacity added per year.
