How is HP calculated?
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252..

Why is 1hp equal to 746 watts?
1Hp = 745.69 Newton meter per second. A 1 hp motor cannot use less than 745.7 Watts so if it uses 1 kW it is about 75% efficient, which sounds about right for a motor of that size. One mechanical horsepower of 550 foot-pounds per second is equivalent to 745.7 watts.
How many cc is a horsepower?
Calculate the horsepower or CC by multiplying or dividing by 15. The general rule is for every 15 CC there is 1 HP. For example, for a 150 CC engine you would take 150 divided by 15, which equals 10 HP.
Why is it called a horsepower?
When the steam engine began to do the work of horses in the mines during the early 1800s, the mine owners began to ask how many horses an engine would replace. James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented.
What is 1hp equal to?
The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.

How do I convert HP to amps?
Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
How many kWh is 1 HP?
1.3404825737Note: Kilowatt-hour (kWh) is a measure of energy and horsepower (hp) is a measure of power. Therefore you can only convert kilowatt-hour (kWh) directly to horsepower hour (hph) or kilowatts (kW) directly to horsepower (hp). 1 kW = 1.3404825737 hp. 1 kWh = 1.3404825737 hph.
What is difference between HP and kW?
James Watt is also the reason we have the measurements watt and kilowatt, most commonly used to measure electricity. Obviously, a kilowatt is 1,000 watts. … To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.
How many watts is a 1/6 hp motor?

Is BHP and HP same?
HP vs BHP. Traditionally ‘brake horsepower’ (bhp) has been used as the definitive measurement of engine power. It’s distinct from horsepower because it takes into account power loss due to friction – it’s measured by running an engine up to full revs, then letting it naturally slow down to a dead stop.
How many watts is a 0.5 hp motor?
A 0.5hp motor uses about 380W of power if it is running at 100% rated load. It can use more power than that if it is under load. If it is not under load it will use less than 0.5hp. In one minute it will use Power x 1/60 Watt hours.

How many watts is a 1hp water pump?
746 wattsIf you have a 1 HP pump (746 watts if you remember your high school physics) a 1000 watt generator is NOT large enough to run your pump. Electric motors require a large amount of power to start.
How many rpm is 1 HP?
5,252 rpmOne horsepower is equal to 33,000 foot-pounds of work per minute. Add in the equations relating to torque and velocity, and you’ll find that horsepower always equals torque multiplied by rpm, divided by 5,252. Canceling out the equal variables, you wind up with horsepower equaling torque… at 5,252 rpm.
