Horsepower is abbreviated to hp. It is a unit of measurement that represents the power of an engine.
Horsepower is not a unit of mass.
The definition of horsepower is a unit of power equal to 746 watts. Therefore, a cow has no horsepower.

No, horsepower is not an SI (International System of Units) unit. It is a unit of power used predominantly in the United States and some other countries to measure the rate at which work is done.
"Foot-lbs" is a unit of energy, whereas "horsepower" is a unit of power,which is the same as the rate of using energy.1 horsepower = 550 foot-pounds per second
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.

By Horsepower if you mean engine ouput ? If so these days it is often expressed in kilowatts rather than horsepower (1HP=0.746kW)
There are no BTUs per horsepower. A British Thermal Unit is an archaic unit of measurement of energy, whereas a horsepower is an archaic unit of measurement for power. As energy and power are two different quantities, you question is akin to asking, "How many miles are there in a mile per hour?"
800 Newtons is equivalent to approximately 0.107 horsepower. Horsepower is a unit of power that measures the rate at which work is done, while Newton is a unit of force.
