How do you get joules?

Multiply the force by the distance. To lift a 98 Newton weight 1.5 meters upward, you'll need to exert 98 x 1.5 = 147 Joules of work. Calculate work for objects moving at an angle. Our example above was simple: someone exerted a force upward on the object, and the object moved upward. read more

Multiply watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. read more

If you want to convert Newtons (force) to Joules (energy) just apply the Newtons over a certain distance, for example lift something. The joules will be the product of the Newtons and the distance. If the force varies, add these products in parts with constant force. read more

Use the value under the column with units of kJ/kg K. Note that kJ stands for kilojoule, one thousand joules, while kg is a kilogram, a unit of mass, and K is Kelvin, a unit of temperature. A change of one degree Kelvin is equal to a change of one degree Centigrade. read more
