## Understanding Watts and Joules

To start with, watts and joules are equivalent units. The first unit is the ampere, and the second is the kilogram. The two are proportional to each other. A volt is one watt over an ampere, and a coulomb is one joule per second. Therefore, a volt is one watt over an amped-up current.

The other unit for power is the watt. This unit is used to measure electrical energy. One watt can produce one coulomb of electricity, which is equivalent to a volt of electricity. The watt is a basic unit of electricity, and it is a common part of electrical equipment. In fact, a single joule can produce as much energy as one watt.

### 1 watt is equal to how many joules mean

A watt is one coulomb of electrical energy per second. The watt-hour is equivalent to the same amount of energy in one second. A 60 kW bulb uses 60 watt-hours of power. A large building owner will want to reduce the number of kilowatt-hours his building consumes in 24 hours. A joule is equivalent to three watt-seconds.

A watt-hour is the equivalent of one joule per second. One watt-hour is about 3,600 joules. A watt-hour is roughly the same as a watt-second. When the two units are compared, a juul is a coulomb. This is a useful comparison to know before using electrical devices in a building.

### A watt-hour

A watt-hour is equivalent to one joule per hour. A 60-watt bulb consumes 60 Watt-hours of power. The amount of energy a 60-watt bulb will consume in 24 hours is measured in kilowatt-hours. By the same token, a building owner wants to minimize the number of Joules consumed in a 24-hour period.

When a watt-hour is used in electrical measurement, the term joule can be written as Wh. Similarly, a yottajoule is one septillion joules, which is about 400 times the total thermal output of the Sun. Another common term for a yottajoules is a yottajoul, which is the same as a yottajoulet.

#### joule

A joule is the SI unit of energy. It is named after James Prescott Joule, the inventor of the first thermometer. It starts with an upper-case letter J, which follows the rules for capitalisation for common nouns. It is not a common noun. The joule symbol is a metric unit of energy, and is often referred to as a calorie.

The SI unit for power is the watt. A tenth of a watt is equal to tenths of a million joules. A tenth of a terajoule is one billion zJ. A tenth of a yoctajoule is one sextillionth of a pound. A sextillion zJ is equivalent to two electron volts.
