work and energy
+++
The Joule (J) is the unit of energy, alone, not of work.
The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
There is no direct conversion between joules and newtons because they are units used to measure different quantities. Newtons measure force, while joules measure energy. However, work, which is measured in joules, can be calculated by multiplying force in newtons by distance in meters.
Energy of heat = Joules (J)
The unit used for ANY type of energy is the joule.
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.

Joules are used to measure energy. Also the related concept of work, which can be thought of as the transfer of energy.

The unit used to measure thermal energy besides joules is the calorie. It is commonly used to quantify the energy content in food and beverages.
All energy is measured in joules.
There is no direct conversion between joules and newtons because they are units used to measure different quantities. Newtons measure force, while joules measure energy. However, work, which is measured in joules, can be calculated by multiplying force in newtons by distance in meters.
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
Energy of heat = Joules (J)
It isn't possible. Joules is the measure of energy and cm is a measure of distance.
Kilo joules are used to measure the amount of energy stored in food.
