Newton To Hp Formula

The following formula is used to calculate horsepower from a force (in newtons) applied over a distance in a given time. 

HP = F*d / (t*745.7)

Variables:

  • HP is the power in horsepower (hp)
  • F is the force in newtons (N)
  • d is the distance over which the force is applied (meters)
  • t is the time over which the force is applied (seconds)

To calculate the horsepower, multiply the force by the distance to get work (joules), then divide by time to get power (watts). Divide by 745.7 to convert watts (the SI unit of power) to horsepower.

How to Calculate Newton To Hp?

The following steps outline how to calculate the Newton to Horsepower conversion.

  1. First, determine the force in newtons (N).
  2. Next, determine the distance over which the force is applied in meters (m).
  3. Next, determine the time over which the force is applied in seconds (s).
  4. Next, gather the formula from above: HP = (F * d) / (t * 745.7).
  5. Finally, calculate the power in horsepower (hp).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Force in Newtons (N) = 500

Distance in meters (m) = 10

Time in seconds (s) = 5
