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.
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 .
1 Horsepower = 746 Watts There is more than one definition of Horsepower, and they have slightly different values.
A metric unit is a decimal unit of measurement of the metric system, based on meters and kilograms and seconds.
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.
A metric unit of measure for volume, often liquids.
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.
105ps likely refers to a measurement of power output in metric horsepower. It is a unit used to quantify the power of an engine, where 1 metric horsepower is equivalent to 0.986 horsepower.

Horsepower is a measure of power, the metric unit of power is the watt. One watt is one joule per second.
10 kilowatts is 13.6 metric horsepower.
The metric unit is a millilitre. The metric unit is a millilitre. The metric unit is a millilitre. The metric unit is a millilitre.
"115 PS" refers to the power output of a vehicle's engine in metric horsepower. It is a unit of measurement used to express the engine's capacity to perform work over a period of time. In this case, it indicates that the engine can produce 115 metric horsepower.
I not a metric unit of anything! A litre is one metric unit for volume.
Metric.

A metric unit is a decimal unit of measurement of the metric system, based on meters and kilograms and seconds.
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.
