The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). ... Therefore, one joule equals one newton•meter.

Each hour 430 quintillion Joules of energy from the sun hits the Earth. That's 430 with 18 zeroes after it! In comparison, the total amount of energy that all humans use in a year is 410 quintillion Joules. For context, the average American home used 39 billion Joules of electricity in 2013.

For any voltage, mAh X voltage x 3.6 = Joules of energy. As we saw above, since a mAh is 1/1000 of an Ah, to convert Ah (amp hours) to Joules just use 1000 x 3.6 = 3600 as the conversion factor instead of 3.6.

While the joule is the SI base unit for energy, when speaking in real-world terms, we often use the kilowatt-hour (kWh) instead. This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it.

Joule (unit) ... One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

In chemistry we measure heat using two different units: calories and joules. A calorie is defined as the amount of energy needed to raise the temperature of one gram of water one degree Celsius. ... The other unit used to measure heat is the joule. The joule is the SI (System International) unit.

The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). ... The amount of energy delivered by a one watt source of power in one second is one Joule.

During the same time period, another 320 joules of energy is lost as heat or utilized in metabolism. This leaves 180 joules for production of new tissues as the caterpillar grows. Dividing 180 by 1000 gives a value of 0.18, meaning that only 18% of the energy taken in by the caterpillar is converted into biomass.

You can therefore estimate that a hot tub with a 120-volt heater will consume 3,000 watts while in use, and one with a larger heater will consume 7,500 watts. These wattages translate into 3 kilowatt-hours (kWh) and 7.5 kWh, respectively.
