1 hp = 746 watts
2 hp = 1,492 watts
2 hp x 1 hour = 1,492 watt-hours = 1.492 kWh
(Note: The "2 hp" rating on the pump refers to the useful output, that is,
the water that the pump moves. The '1.492 kWh' calculated is simply the
equivalent of 2 hp-hour, expressed in a different unit. The consumption
from the electric utility will be more than that, because no machine is
100% efficient, that is, a machine's useful output work/energy is always
less than the input to it.
To calculate the input energy required to operate this pump at full load
for an hour, divide 1.492 kWh by the efficiency of the pump.)

Is the abbreviation for kilowatt hour?
KWH
How do you convert gallon per kWh to liters per hour?
The two sets of units are not compatible. While a gallon may be converted to a litre, there is no relationship between kWh and hour.
How many units consumed per 24 hours of megawatt mot er?
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
How much energy does a 60 watt bulb use per hour?
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
How many electron volts per kilowatt hour?
One kWh has 2.25 x 1025 eV. (The electron-volt is a very small unit, used in particle physics.)
How many kWh in a cubic meter of water?
kWh stands for kiloWatthours, the amount of electrical energy an appliance uses or generates in one hour measured in kiloWatts. It has nothing to do with one cubic metre of water.
How many Kwh to raise 1 l water 1 degree c?
It takes approximately 1 kilowatt-hour (kWh) of energy to raise 1 liter of water by 1 degree Celsius. This is a common measure of energy for heating water in many applications.
How many kWh in a tWh?
There are 1 million kilowatt hours (kWh) in one terawatt hour (tWh).
How many watts are in a kwh?
A 1000 watt device operated continusouly for 1 hour would equal 1 Kwh.
How many joules are there in one kWH?
There are 3.6 million joules in one kilowatt-hour (kWh).
How many kWh will a 200watt solar panel create?
Assuming the solar panel operates at full capacity for one hour, it would produce 0.2 kWh (200 watts * 1 hour = 0.2 kWh).
How many kWh on watt?
KWH stands for kilowatt hour, meaning a thousand watts used for an hour. In terms of, for example, the familiar 60 watt light bulb, you would need (just under) 17 such light bulbs operating for an hour to consume 1 KWH.
How many units of electricity does a 3000w heater use in an hour?
A 3000 W water heater is 3 kW water heater. For 30 minutes of operation it would be 3 kW multiplied by 0.5 hours, or 1.5 kWh. One kWh is equal to 3,600,000 Joules, the water heater uses 1.5 times 3,600,000 J, or 5,400,000 J.
How many rotations make 1 kwh?
One kilowatt-hour (kWh) is a unit of energy, not rotation. It represents the amount of energy consumed when one kilowatt of power is used for one hour. The concept of rotations does not directly translate to kWh.
How many joules are in a kWh?
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
How many kWhs are there in a kW?
kWh is usage, while kW is power. One kW for one hour is one kWh, one kW for 30 minutes is 0.5 kWh ASO
How many kwh in 1 unit?
There are 1 kilowatt-hour (kWh) in 1 unit of electricity. The terms "kWh" and "unit" are commonly used interchangeably to measure electricity consumption.
