Convert Terawatts to Microwatts
Convert Terawatts (TW) to Microwatts (µW) instantly and accurately.
Conversion Formula
µW = TW × 1.000000000e+18
About Terawatts
A terawatt (TW) is 10¹² W. All of human civilisation consumes ~17-18 TW (electricity + heat + transport combined); global electricity generation alone is ~9 TW. Solar irradiance intercepted by Earth is ~174,000 TW; photosynthesis captures ~130 TW. The National Ignition Facility (NIF) fusion laser produces pulses of ~500 TW lasting nanoseconds. High-power laser facilities for nuclear physics and ICF research routinely exceed 1 TW in ultrashort pulse regimes. 1 TW = 10¹² W.
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.
