### What is the equation of converting horsepower to joule?

Horsepower is a unit of power, but joules is a unit of energy.
To convert horsepower to joules, you need an additional time
parameter. One horsepower is about 745.7 watts. So a
horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules.
A horsepower-hour is then 745.7 times 3600 = 2684520 joules.

### How many joules are used to produce light in a 100 watt light bulb?

Joule is the unit of energy. Watt is the unit of power. One
Joule provides one Watt for one second. A 100 Watt lamp uses 100
Joules per second.
Answer
Power is the rate of doing work. Work is measured in joules, so
power is measured in joules per second. However, in SI, a joule per
second is given a special name: the watt. So a 100-W lamp consumes
100 J of energy per second.

### 1 mole is how many joules?

The mole is a unit of quantity of matter, whereas the Joule is a
unit of energy.
The relation depends on the substance, and what you wish to do
with it. If you had a single mole of one substance and a mole of
another and they were stoichiometrically combined, then the energy
from the reaction could be calculated, and that could be expressed
in Joules.
On the other hand, you could also use the equation E=mc2 to

### How do you calculate energy in kilojoules?

REMEMBER that energy is neither created or destroyed but changed
from one form to another. Kinetic energy (known as the energy
during a motion) is the result of potential energy (stored energy
by different means, by mechanical means or due to gravity). Joules
is the unit of measuring the packet of energy, and kilojoules is
just a bigger unit. 100J is 0.1kJ.

### How many joules equals one horsepower?

OK these are known
1 HorsePower= 746 Watt
1 Watt= 3.413 BTU
by multiplying how many watts in an HP (746) by how many BTUs in
a watt (3.413)
we know 1 HP=2546 BTU
there are 1055 Joules in 1BTU
so multiply how many joules per 1 BTU (1055) by how many BTU in
1 HP (2546)
and you get
2,686,133.4 Joules per 1HP
