If one knows the bore and stroke, which are easily measured, an estimate of the horsepower rating of an engine can be obtained by using the given chart. Multiply the torque by the engine speed, and then divide that number by 5252. This free engine horsepower calculator estimates vehicle engine horsepower using two different methods, the elapsed time method and the trap-speed method.

For reasons of simplicity let's take an engine that makes 300 HP. These calculators are for entertainment value only.
For converting HP to volts we have three sets of the formula for DC, AC single-phase and AC three-phase. This calculator will help you estimate the potential of an engine. Hydraulex is a family of Attica Hydraulic Exchange, Flint Hydrostatics, Hydraulic Repair and Design and Metaris Hydraulics. We use a simple formula to calculate horsepower. If we at GoFastMath.com see a demand for this horsepower calculator to also work for boosted engines, we will do our best to make that happen. Another common unit of power that motors are rated in is watts. Back in the 18th century James Watt was developing steam engines and wanted to come up with a unit of measurement that would indicate the amount of workhorses the steam engine would . The calculator says that 0.08 hp (60 watts) is sufficient.

and 10 amps is: HP = (120 x 10) / 745.7. horse-power of the car can be calculated byspecial formula.formula is reduce to simple form, so that it is easy to remember=====. Horsepower = (Torque × Speed) / 5252. You will be using the formula (RPM x T)/5252=HP, where RPM is the engine speed, T is the torque, and 5,252 is radians per second. 1% less than the effective engine power. To use this horsepower calculator enter the mph trap speed at the 1/4 mile mark from one of your dragstrip ET slips. Solution: Hp to volts Calculation: HP is the short form of horsepower. The more horsepower and the less weight, the better it will perform.
