# What is watt?

Watt is a unit of measurement that is part of the International System. The term, synonymous with the English word watt, is used in power measurements and is equivalent to one joule per second.

The watt, which has the W as its symbol, is a tribute to the British mathematician and engineer James Watt, who was born in 1736 and died in 1819. Watt was largely responsible for the development of the steam engine. One of the areas in which the watt is used as a unit of measurement is in the field of electricity. The electrical power of a device can be expressed in watts and, if it has a lot of power, in one of its multiples (such as kilowatts or megawatts).

The idea of ​​electrical energy refers to the rate of generation or use of energy in the execution of a work. If we have an 80-watt light bulb lit for sixty minutes, we will have consumed 80 watt-hours. It should be noted that the watt-hour reflects power over time (the amount of energy generated to maintain a given power for a given time). We said in the lines above that one watt is equal to one joule per second: that device that consumes one watt of electrical energy will be consuming one joule per second. If the light bulb consumes 80 watts for one hour, it will consume 288,000 joules in that period. 80 watts in an hour = 80 joules per second x 3600 (in every hour there are sixty minutes; in every minute, sixty seconds. Therefore: 60 x 60 = 3600) 80 watt-hours = 288,000 joules The power of machines, engines and power plants of power is usually expressed in watts or kilowatts. These units, in turn, have equivalents in horsepower and horsepower, to name two possibilities. In addition to all this, we must emphasize that on numerous occasions and by people of very different types, confusion is created regarding the watt. Specifically what we are referring to is that they are able to confuse it with the volt (V) since both terms are used within the electronic and electric field. To avoid falling into this error, and starting from the explanation we gave about the watt, it is necessary to know that the volt refers to voltage or potential voltage. That is, it is the difference in electric potential that exists between two specific points. To understand and make it clear: one, therefore, is a voltage term and the other is a power term. Likewise, we cannot ignore that watt is a word widely used in the field of sport and, more specifically, in the world of cycling. In this sector it is used to refer to the measure of force that registers the force that the cyclist exerts to be able to move his bicycle. In order to know the above-mentioned force, it is usual for the two-wheeled vehicle to place electronic devices in the transmission area in particular.
