Vatsat (znak: Wh) mjerna je jedinica izvan SI čija je primjena dopuštena i uobičajena za iskazivanje vrijednosti električne energije u elektroenergetskom sustavu. Jedan vatsat je energija koju utroši potrošač snage jedan vat za vrijeme od jednog sata:

1 Wh = 1 W · 1 h = 1 W · 3600 s = 3600 J

U praksi se uglavnom susreću decimalni višekratnici:

  • kilovatsat, 1 kWh = 1000 Wh
  • megavatsat, 1 MWh = 1×106 Wh
  • gigavatsat, 1 GWh = 1×109 Wh
  • teravatsat, 1 TWh = 1×1012 Wh
