Oblicz : 12700J =....... kWh 20kJ=.........kWh 1,7mJ=........kWh Proszę o pomoc ! ;(

12700J/3600000J= 0,00352 Kilowatogodzina [kWh] 20kJ=20000J/3600000J=0,0056 Kilowatogodzina [kWh] 1,7MJ=1700000J/3600000J=0,4722 Kilowatogodzina [kWh] Licżę na najlepsze :).

1 000 J = 1 kJ 1 000 000 J = 1 MJ 1 J = 1 Ws = 0,001 kWs = 0,001 kW *(1/3600h) = 0,00000028 kWh 1 kJ = 0,00028 kWh 1 MJ = 0,28 kWh    12 700 J = 12,7 kJ = 12,7 *0,00028 kWh = 0,0035 kWh 20 kJ = 20 *0,00028 kWh = 0,0056 kWh 1,7 MJ = 1,7 *0,28 kWh = 0,476 kWh
