It is a unit of work or energy. Watts are a unit of power or energy per second. Watts times seconds is energy, thus the 'h' hours of kWh is what turns power to energy.

What is the unit of energy power consumption?
kWh is equivalent to 3.6×106 J
How do you Convert refrigeration tons to kWh?
4.5 tons of refrigeration is a unit of power while kwh or kw-hr is unit of energy. Its not possible. Maybe you mean kw only not kwhr. 1ton of ref= 12000btu/hr = 3.51 kw
What is SI and commercial unit of energy?
The SI unit of energy is Joules The commercial unit of energy is KiloWaltHour(KWh) The relationship between SI unit and commercial unit is: 1 KWh=3.6*106J (or 3600000 J) One KiloWaltHour is: 1kWh = 1kW * 1h And the definition for kWh is: 1kWh is the electric energy consumed by an appliance of power 1 whenit is used for one hour
What is one unit in physics?
Electricity is measured in Kilowatt hours or for the symbols kWh
What is the abbreviation 1W?
In electronics, a capital W is the abbreviation for Watt. A Watt is a unit of electrical power. A quantity of electrical power is usually expressed as the amount of Watts consumed over a period of time. For example: kWH (kilowatt per hour)
Is a kWh a unit of power or unit of work?
kWh (kilo watt hours) is a unit of energy.W is a unit of power and h is a unit of time. power x time = work. Therefore kWh is unit work, or energy. The k is no unit at all, it is simply short for kilo, a multiplier by one thousand.
Is kWh a unit of power or a unit of work energy power or more than one of these?
Energy is measured in Joules and is generally defined as the potential to do work. Power is the rate of energy usage (Watts) or (Joules per second). A kWh is also a unit of energy (1000 W * 3600 seconds = 3600000 J)
Can the google calculator do unit conversions?
"Yes, it can. But some units will not convert to others such as KWH into horsepower, as they deal with slightly different things. KWH is energy and horsepower is power, so that won't work"
What is the unit of Bond's Work Index?
Kwh per ton
What is the unit of energy power consumption?
kWh is equivalent to 3.6×106 J
Difference between kw and kwh?
KW is the unit power KWh is the unit of electrical energy KW or Watt defines the rating or power of a electrical equipment. For ex: motors, heaters etc. KWh is a measurement that how much energy is been consumed by the electrical equipments. Generally, operating 1KW rated equipment for an hour measures one KWh. Energy meters are the instruments for this purpose
Why you take energy bill in units of energy instead unit of power?
Energy bill must be in terms of Energy unit (KWH) only. Energy is KW (power) utilized over a period of time. The unit of energy is Kilowatthour (KWH) Unit of power is Kilowatt (KW) KW is instantaneous power being utilized. KW (power) over a time period is Energy (KW H)
Is kWh a unit of energy?
Yes, kwh is a unit of energy.
What is the base unit for power?
The kilowatt.hour (kWh)More detailsNo matter whether we are talking about electrical work or mechanical work, in engineering all measurements of actual work done are measured as the power used over a period of time.The standard unit used to measure power in electrical engineering is the kilowatt and time periods are measured in hours, so the work done is measured in kilowatt.hours (kWh).Exactly the same unit is used to measure amounts of energy used.The energy transfer from a source of power to produce an end-result of work done can never be 100% efficient so the energy used (measured in kWh) will always be more than the actual work done (also measured in kWh).A further factIn the United Kingdom, electricity companies charge their customers by the unit. The term 'unit' is short for the obsolete expression 'Board of Trade Unit' and is a measurement of electrical energy, equivalent to a kilowatt hour. So, 1 unit = 1 kW.h.
Is there a difference between KW and kW?
AnswerKiloWatt 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.
Do you measure large currents in kwh?
No, current is always measured in amperes (A). watt hours is the unit for power.
What units are used in electric utilities?
Kilowatt-hour (KWh) which is an energy unit equivalent to a power of 1000 Watts running for 1 hour = 1000x3600 Joules =3.6million Joules. 1 kWh is sometimes called in the trade " 1 unit".
