1kwh= 1000w×3600s
=360000ws
=3.6×10 power 6
1kwh=3.6×10 power 6 J ( 1J= 1ws)

⭕️In simple words :-

1 Kwh = 1000 W x 3600s
(1 hr) 
           
= 3600000 J
         
= 3.6 x 10^6 

⭕️In detail!!!! :-

⭕️Commercial unit of energy = kWh

⭕️ SI unit of energy= J

∴ commercial unit = si unit

∴ J  = kWh                                                                                   
 ⇒ J =1kW x 1h
​                                              
 ⇒ J =1000W x 30x30 
   
➖ 1kWh=1000W
 
➖1hr = 30 ×30s
                                              
 ⇒ J= 1000W x 3600
                                             
 ⇒ J = 3600*1000                    
                                             
 ⇒ J = 3.6×10^ -6  

➖1 unit of energy means 3.6×10^-6 

⇒∴  1kWh = 1 unit
