About Gigawatts
A gigawatt (GW) is 10⁹ W - the scale of national grid capacity. UK peak demand is 40-70 GW; France 80-100 GW. Japan's Kashiwazaki-Kariwa nuclear complex totals 8.2 GW. World installed solar PV surpassed 1,000 GW in 2022. The North Sea Link Norway-UK undersea cable carries 1.4 GW. Global data centre consumption exceeds 200 GW. A lightning bolt peaks at ~1 GW for ~30 µs, yielding only ~250 kJ total energy - power is extreme, energy modest. 1 GW = 10⁹ W.
About Kilocalories per Hour
One kilocalorie per hour (kcal/h) equals exactly 1.163 W. It is the natural unit for human metabolic rate: sedentary adult ~60-70 kcal/h; walking 250-350 kcal/h; vigorous cycling 500-700 kcal/h; competitive rowing ~1,200 kcal/h. Treadmills and exercise bikes display kcal/h directly. Industrial drying and evaporation calcs in older metric systems (especially Asia) used kcal/h for heat duty; 1 Mcal/h = 1.163 kW. 1 kcal/h = 1.163 W.
