10 Best Free Online Horsepower Calculator Websites

Here is a list of best free online horsepower calculator websites. Horsepower is a measurement of the rate at which work is done. Horsepower is mainly used to define the power of engines and motors. There are various variations of horsepower like metric horsepower, water horsepower, boiler horsepower, boiler horsepower, and more. Each horsepower variant requires different sets of input values to perform the calculation like Engine Horsepower requires Torque and Speed (RPM) as input, Water Horsepower requires Flow Rate and Total Head as input. If you also want to calculate different variations of horsepower, then check out these online horsepower calculator websites.

These websites allow users to quickly calculate the horsepower of engines and pumps. To do that, users just need to enter the required input values. According to the requirement, users can also specify the SI unit of both input parameters and output horsepower (HP, KWH, etc.). Most of these websites also show the horsepower calculation formula that they use to perform the calculation. To help out novice users, I have also included the steps of HP calculation in the description of each website.
