### How many watts does a washing machine consume in an hour?

The same as it consumes in a second, or in a minute. Please note that a watt is a unit of power, not a unit of energy. Power means energy per time unit. To get the details, you can check the electrical specifications on your washing machine. Most such electrical devices have a metal plate with the electrical specifications written on it - perhaps on the device's back.

### How is the kilowatt hour used?

The kilowatt is a unit of power (energy / time); the kilowatt-hour is a unit of energy - the energy equivalent to the power of 1 kW, during one hour. The kilowatt-hour is equivalent to 3.6 x 106 Joule (a Joule is the same as a Watt-second). The kilowatt-hour is commonly used as a unit to charge for electrical energy. Note that you pay for electrical energy, not for electrical power.

### 1 unit of power equal to how many watts?

A unit is not used to measure power, but energy. A unit is used by British electrical companies to measure energy consumption, and is short for 'Board of Trade Unit'. A unit is equivalent to a kilowatt hour. A watt, on the hand, is used to measure power, not energy -so you cannot relate a unit to a watt.

### What is 100 watts?

Watts is a unit of power that is equal to volts x amps x Power Factor. Answer The watt is the SI unit for power. Power is defined as 'the rate of doing work'. Since work is measured in joules, the watt is equivalent to (a special name given to) a joule per second. The watt is sometimes described as measuring 'electrical' power. In fact, there is no such thing as 'electrical' or 'mechanical' (etc.)…

### What is the SI unit of power?

The SI units for mechanical and electrical Power are the Watt (W), and the Watt (electrical) (We) respectively. Power is the rate of doing work, or at which energy is converted. It can be thought of as - "amount of energy used to perform work, or converted from one form to another, in a specified period of time, namely, in a second". The equation is P=W/t, where P is Power, W is the work done…

### What is electrical horsepower?

Horsepower is simply the Imperial unit of measurement for power. To a large extent, this has now been replaced by the SI unit, the watt. For example, car engines are now rated in kilowatts rather than horsepower. One horsepower is equivalent to 746 watts. Power is simply the rate of doing work. There is no such thing as 'electrical power', 'mechanical power', etc.

### What is the unit of electrical measurement?

This question is not at all crystal clear to understand because there are so many different things which can be measured when considering electrical circuits and equipment! Please see the answer to the Related Question for more information. However, if you are asking about the unit to use for measuring an amount of electrical energy to be paid-for, many electric power utility companies charge their customers by 'The Unit'. The term 'The Unit' is short…
