Convert Microwatts to Gigawatts
Convert Microwatts (µW) to Gigawatts (GW) instantly and accurately.
Conversion Formula
GW = µW × 1.000000000e-15
About Microwatts
A microwatt (µW) is 10⁻⁶ W - the operational power band for autonomous IoT sensors and energy-harvesting wearables. Quartz oscillators in microcontrollers consume 1-10 µW; thermoelectric wearables harvesting body heat produce 10-100 µW. NFC tags derive ~10-200 µW from the reader field. Cochlear implants and implantable glucose sensors operate at microwatt levels to minimise tissue heating. 1 µW = 10⁻⁶ W.
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.
