WebA Joule is officially the amount of energy required to exert a force of 1 Newton through a distance of 1 meter. So one Joule equals 1 Newton-meter or 1 N-m (1 J = 1 N-m). That's the mechanical definition. Thermal energy can also be defined, as we show a couple of paragraphs below. A Joule is not a lot of energy, unless you're a hummingbird. Web1 Watt is equal to 1 joule per second. So a chocolate bar might have 800,000 joules of energy in it (roughly 200,000 calories). If you use this energy at a rate of 1 watt, it'll take you 800,000 seconds to use it all up, because 1 watt = 1 joule per second. Joule (and calories) are units of energy while Watt is a unit of power.
