Power(watts) = Voltage x Current W = E x I Power(watts) = Voltage² / Resistance W = E² / R Power(watts) = Current² x Resistance W = I² x R KW(kilowatts) = W / 1000 mw(milliwatts) = W x 1000 
VA = Voltage x Current VA = E x I Power(watts) = Voltage x Current x Power Factor W = E x I x PF KVA = VA / 1000 KVA = E x I / 1000 KW(kilowatts) = Voltage x Current x Power Factor / 1000 KW = E x I x PF / 1000 
VA = voltage x Current x 1.73 VA = E x I x 1.73 Power(watts) = Voltage x Current x 1.73 x Power Factor W = E x I x 1.73 x PF KVA = VA/1000 KVA = E x I x 1.73 / 1000 KW(kilowatts) = Voltage x Current x 1.73 x Power Factor / 1000 KW = E x I x 1.73 x PF / 1000
