KiloWatt hours. Its a measure of energy use. It is the amount of power used over time.
Energy is the ability to do work, while power is the rate at which work is done.
Your water heater may have a power rating of 5 kW. If it runs for 8 hours in a day, you would use 40 kWh of energy doing the work of heating the water.
Kw is the unit used for Power whereas KWh is the unit used for Energy
Energy = Power * Time
Units = No. of hours of operation * Power in Kw
CommentThe correct symbols are 'kW' and 'kW.h'.
Both mean kilowatts.
The usual notation is kW.
no difference
Kc is the constant for concentration and Kw is the constant for water. Kc[h20] = [OH-][H+] which becomes Kw= [OH-][H+]
If the town has natural gas for heating, then the power needed per household is between 5 kW and 10 kW. If only electric heat is available, then the combination of electric resistance (auxiliary - from 7 to 10 kW for small residential units) heating, combined with electric clothes dryer (from 2 to 5 kW), electric water heater (from 2.5 to 7.5 kW), and stove (5 kW to 7.5 kW) totaling a min of 15 kW to a max of 20 kW. That would put the max power requirements between 5,000 kW and 10,000 kW. As a matter of reality, a diversity factor of .6 to .7 would reduce the max power to 3,500 kW and 7,000 kW.
Both of them are for measurements of types of energy. kWh is the full measure of energy while kW is the measure of power.

What is a "kw"?
Mean power is measured in Watts and Peak power is measured in KW.
KVA=KW*Power factor, considering PF 0.9, 6KVA=KW*0.9 KW=6/.9=6.67
1 kw =1000w 101 kw=101*1000=101000watts
kVA = kW divided by (power factor). The power factor is the cosine of the angle between voltage and current.
