## How does this horsepower calculator work?

This is a useful tool when in need to estimate power in watts and kilowatts as well as the equivalent in mechanical horsepower, metric, electrical or boiler horsepower.

There are three variables to be taken into account and then used in the formula below:

Force – expressed in either Newton, kilonewton, dyne, kilogram force, pound force or poundal;

Distance – expressed in either meter, kilometer, mile, yard, feet or inches;

Time – expressed in either second, minute, hour or day.

As you can see there is a large variety of combinations you can make for your determination as the horsepower calculator will make the necessary conversions for you while employing the formula.

In regard to the horsepower result, you will be offered a series of conversions so you can discover the most used units in just one sentence.

## Horsepower formula and conversions

Power = Force * Distance/Time

Where:

Power is measured in watt.

Force is measured in Newton.

Distance is measured in meter.

Time is measured in seconds.

 Force 1 newton equals other units to newton 0.001 kilonewtons 1 kilonewton = 1000 newtons 100 000 dyne 1 dyne = 1.0 x 10^-5 newtons 0.101971621 kg force 1 kg force = 9.80665 newtons 0.224808943 lbs force 1 lbs force = 4.44822162 newtons 7.23301408015 poundal 1 poundal = 0.13825 newtons Distance 1 meter equals other units to meter 0.001 kilometres 1 kilometer = 1000 m 0.000621371192 miles 1 mile = 1 609.344 m 1.0936133 yards 1 yard = 0.9144 m 3.2808399 feet 1 foot = 0.3048 m 39.3700787 inches 1 inch = 0.0254 m Time 1 second equals other units to second 0.0166667 minutes 1 minute = 60 s 0.000277778 hours 1 hour = 3600 s 1.1574e-5 day 1 day = 86,400 s

The power in watts is converted in kilowatts as well, so the calculator converts 1 watt to 0.001 kilowatts. Moreover the result displays the power converted to different horsepower units by applying the following conversion rates:

• 1 watt = 0.00135962162 horsepower (metric)
• 1 watt = 0.0013404825737265 electrical horsepower
• 1 watt = 0.0013410889041094 mechanical horsepower
• 1 watt = 0.0001019419950048 boiler horsepower

## Example calculation

Force = 12,560 newtons

Distance = 45 yards

Time = 36 seconds

Result:  Power = 14,356.08 watt or 14.36 kilowatt

A power of 14,356.08 watt is approximate equal to 19.52 horsepower (metric) or to 19.24 electrical horsepower or to 19.25 mechanical horsepower or to 1.46 boiler horsepower
