a.  1 J = ...kWh 1 J = 1 W·1 s 1 W = 1/1000 kW 1 s = 1/3600 h 1 J = 1/1000 kW · 1/3600 h 1 J = 1/3600000 kWh b. 1 kJ = ... kWh 1 kJ = 1000 J = 1000 W·s = 1 kW·1/3600 h = 1/3600 kWh 1 kJ = 1/3600 kWh c. 1 MJ = ... kWh 1 MJ = 1000000 J = 1000000 W·s = 1000 kW·1/3600 h = 1000/3600 kWh 1 MJ = 1000/3600 kWh = 10/36 kWh = 5/18 kWh 1 MJ = 5/18 kWh d. 12700 J = .... kWh 1 J = 1/3600000 kWh 1 12700 J = 12700·1/3600000 kWh = 12700/3600000 kWh  =127/36000 kWh 12700 J = 127/36000 kWh e. 20 J = .... kWh 1 J = 1/3600000 kWh 20 J = 20·1/3600000 kWh = 20/3600000 kWh = 1/180000 kWh 20 J = 1/180000 kWh f. 1,7 MJ = .... kWh 1,7 MJ = 1700000 J 1 J = 1/3600000 J 1,7 MJ = 1700000 · 1/3600000 kWh = 17/36 kWh 1,7 MJ = 17/36 kWh g.  1 kWh = .... J 1 kW = 1000 W 1 h = 3600 s 1 kWh = 1000 W·3600 s = 3600000 W·s = 3600000 J 1 kWh = 3600000 J h.  2 kWh = ..... J 1 kWh = 3600000 J 2 kWh = 2·3600000 J = 7200000 J 2 kWh = 72000000 J i.  15,2 kWh = .... J 1 kWh = 3600000 J 15,2 kWh = 15,2·3600000 J = 54720000 J 15,2 kWh = 54720000 J j.  0,08 kWh = ... J 0,08 kWh = 0,08·3600000 J = 288000 J 0,08 kWh = 288000 J k.  153 kWh = .... J 1 kWh = 3600000 J 153 kWh = 153·3600000 J = 550800000 J 153 kWh = 550800000 J l.  12,07 kWh = ... J 1 kWh = 3600000 J 12,07 kWh = 12,07·3600000 J = 43452000 J 12,07 kWh = 43452000 J
