What is watios o vatios?

Watios or vatios are a unit of measurement used to quantify power or the rate at which energy is transferred. It is named after the Scottish engineer James Watt and is defined as the amount of energy transferred or converted per unit time. One watt is equivalent to one joule of energy transferred per second. The unit symbol for watt is W, and it is widely used in electrical engineering, physics, and other fields related to energy and power. The watt is also used to measure the power of electrical appliances such as light bulbs and motors. It is a useful unit of measurement in assessing the energy efficiency of devices, and is often used in discussions of energy consumption and conservation.
