Zamiencie mi 2700000 J(dzuli) na kWh(kilowatogodzina)

1 kWh = 1000 J/s *3600 s = 3600000 J  1 kW = 1000 W = 1000 J/s 1 h = 3600 s układam proporcję : 1 kWh = 3600000 J x kWh = 2700000 J x = 2700000 / 3600000 x = 0,75 kWh

[latex]1 kWh = 1kW 8 1h = 1000W * 3600s = 3 600 000 J\\1 J = frac{1}{3600000} kWh[/latex] [latex]2 700 000 J = frac{2700000}{3600000} kWh = 0,75 kWh[/latex]
