    1kw is read as kilowatt and is the unit of power.

    Indicates how much work is done per unit of time.

    It can also be said to be the speed of the work.

    Let's be specific.

    The more power, the faster the work.

    For example, boil as much boiling water.

    If you use a high-powered electric kettle, then it will definitely burn faster.

    Another example is eating hot pot.

    One hot pot power is 2kw and the other is 1kw

    Obviously, the 2kw hot pot cooks faster, and of course it tastes much cooler.

    But obviously there is more electricity consumption.

    Let me tell you about the popular point in life, which means that it means one kilowatt-hour of electricity.

    It is the result of the accumulation of frozen stickiness on tree branches and other objects by countless fog droplets below zero degrees Celsius in the fog, which appear as white opaque granular structure deposits. Therefore, the rime phenomenon is very common in the north of our country, and it is also common in the southern alpine areas, as long as there are cooling water droplets in the fog.

    1 kilowatt·hour (kw·h) = 3,600,000 joules (j).

    The units of work are joules and kilowatt hours, and the relationship between them is as follows:

    1 joule = 1 watt second, 1 kWh = 1 kW 1 hour = 1000 watts 1 hour = 1000 watts 3600 seconds = 3600000 joules. i.e.: 1 kWh = joule.

    The letter units are expressed as follows:

    1kw h=1kw h=1000w h=1000w h=1000w 3600s=3600000j (j is the sign for joules, the basic unit of work).

    Expand the Kai Noisy Exhibition Information:

    Electrical power is used to express how fast or slow the electrical energy is consumed (the unit of electrical power is watts or joule seconds). Also commonly used 瓩 = kilowatt). The active power is denoted by a capital p in the formula.

    Electrical work is often also the manifestation of electrical energy in electricity, so kilowatt-hours are usually the unit of electrical energy. Electrical work is represented by a capital w in the formula.

    The formula for electric power: p=w t (t in the formula represents time, the basic unit is seconds-s, and the unit hour-h is also commonly used to calculate) The formula for measuring electric power: p=ui (u in the formula represents voltage, and the basic unit is volts-v; Uppercase i indicates current, and the base unit is ampere-a).

    According to Ohm's law: U=IR (r in the formula represents resistance, and the basic unit is ohm-).

    About the conversion of kilowatt-hours units:

    1) Kilowatt-hour is equal to: metric horsepower-hour.

    2) Kilowatt-hour is equal to: Imperial horsepower-hour.

    3) Kilowatt-hour is equal to: kilocalories.

    4) Kilowatt-hour is equal to: British thermal units.

    KWh. A single companion town code point that represents electrical energy.

    One is that electrical appliances consume the electrical energy of the brigade, that is, the electrical energy consumed by l kilowatts in one hour.

    The other is the power capacity of the battery, that is, the electrical energy stored by the battery can be used for one hour of operation of a kilowatt electrical appliance.

    kW is an internationally unified unit of power.

    Power is a measure of the amount of force output per unit of time.

    It can also be said to be the speed of the work.

    Take the top male cyclist as an example, 5s sprint, maximum output.

    The average output power that can be achieved for a long time can be approximately. And ordinary people who have not been trained, it is difficult to exceed 1kw output if they pedal desperately, and the average output that can persist is below.

    We are familiar with the BMW X5

    The turbocharged engine has a maximum power of 224kw, which can output the power of almost 1000 ordinary people, and it is tireless.

    An SUV needs about 20kW of power when cruising at 100km H, while cruising at 120km H, it needs about 40kW of power. That's why cruising at 90kmh is very fuel-efficient, and when you get faster, your fuel consumption increases quickly, because when you get faster, the drag on the car increases dramatically.

    W is the unit of power, 1KW = 1000W

    1W = 1V*1A, that is, the voltage of the electrical appliance is 1V, and the current passing through the working time is 1A.
