Horsepower is just a calculation of how much work an engine can do over time. An engine actual doesn't make horsepower, an engine makes torque, the force that turns the crankshaft. HP= torque x rpm it is produced at/ 5252rpms
An example: a motor that produce 300 ft-lbs @ 4000 rpms the horsepower at that rpm is 228.5hp@ 4000rpms A horse can lift 550 pounds at the rate of one foot per second. In other words, it could lift 33,000 pounds one foot per minute. And that's the figure we use today: one unit of horsepower equals 33,000 foot-pounds per minute. the horse power is obtained by mechnical means is called "bhp", (brake horse power) 1 HP = 746 watts
Another Answer
The horsepower is the Imperial unit for power. The SI equivalent is the watt. A horsepower is equivalent to 746 W. It's completely incorrect to argue that the horsepower measures mechanical power and the watt measures electrical power, as they are completely interchangeable. You can measure the power of an electric heater in horsepower, if you wish, and you can measure the output power of a car engine in watts.

What is the metric equivalent of the US unit of horsepower?
The metric unit of power is the 'watt', and of course its power-of-ten multiples and submultiples are used where necessary to produce convenient numbers. Probably the closest to the horsepower is the 'kilowatt' = about 1.3405 HP .
What is 1 horsepower equal to in the Metric system?

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 do you convert ton into horsepower?
There is no direct conversion between ton and horsepower since they measure different things. Ton measures weight or mass, while horsepower measures power or work rate. However, if you are referring to metric ton (tonne), you can use a formula to convert it to a unit such as kilowatts, which is a measure of power like horsepower.
How do you calculate hp OF ENGINE in metric system?
You don't, because horsepower is not a metric unit. Horsepower is a unit of work, so the metric equivalent would be the watt. There are several different definitions of horsepower, which work out to somewhere between about 730-750 watts depending on precisely which one you use.
What does 105ps mean?

What does kw in car engine means?
A kilowatt is the metric unit for power. A horsepower is the Imperial unit for the same thing. So there's absolutely no reason why a kilowatt shouldn't be used to measure the output power of a car engine in the same way that a horsepower was. In fact, outside the US, most countries rate their car engines in kilowatts not in horsepower.
