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
Answer
You are comparing apples with Oranges. A horsepower is the Imperial unit of measurement for power, whereas the joule is the SI unit of energy. Power and energy are two different quantities, so you cannot convert one to the other. Further to the original answer, there are no 'BTUs in a watt' because, again, a BTU is used to measure energy, whereas the watt is used to measure power.
So the simple answer is you cannot convert joules to horsepower.

How many watts of electrical power equal one horsepower?
746W = 1Hp
What is the different of kw and horse power?
Only the size. One Horsepower = 746 watts.
1 HP is equal how many electrical watt?
1 horsepower = 745.699872 watts
How are watts measured?
Electrical power is measured in watts. In an electrical system power (P) is equal to the voltage multiplied by the current.P = VxI Watts = Volts x Amps.
How does horsepower relate to Watts and power?
Horsepower is seldom used when referring to electricity because it has a couple different definitions i.e. Mechanical Horsepower, Metric Horsepower, Electrical Horsepower etc. In general 1 Mechanical Horsepower would = 745.6999 Watts.
How many watts of electrical power equal one horsepower?
746W = 1Hp
How many watts of power are equal to 1 horsepower?
The definition is that 746 watts equal one horse-power.
Electrical power is expressed in watts or?
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
What unit is used to express electrical power?
Electrical power is also measured in Watts.
What is the different of kw and horse power?
Only the size. One Horsepower = 746 watts.
1 HP is equal how many electrical watt?
1 horsepower = 745.699872 watts
How much horsepower does a cow have?
The definition of horsepower is a unit of power equal to 746 watts. Therefore, a cow has no horsepower.

If a car engine is rated at 125 horsepower how many watts of power does it produce?
1 horsepower is equal to 747.5 watts. 125 hp therefore = 93.2kW
Watts and horsepower are both units of what?
Watts and horsepower are both units of power.
How many watts does it take to equal ten horsepower?
A horsepower is equal to 746 watts, so 10 x 746 = 7,460 watts.
