The Horsepower calculator gives an estimate of vehicle(car, truck, motorcycle) engine horsepower, torque and other engine computations. Additionally supplied are five helpful converters for US/Imperial and Metric units.

Also, you are buying a reference for common CNC Programming G-Codes and M-Codes. It is useful to machinists, engineers, programmers, teachers and students.

Horsepower Calculators

- Trap Speed
- Estimated Time
- Torque/Engine Speed

The Trap Speed method uses the gross weight of the car, including the driver, and the speed at which the car completed the quarter-mile run, which is 1330 feet or 0.405 kilometers.

The Estimated Time method uses the gross weight of the car, including the driver, and the time it took that car to travel the quarter-mile run, which is 1330 feet or 0.405 kilometers.

The Torque speed method uses the torque in foot-pounds times the engine speed in revolutions per minute, RPM, divided by 5,252 to get the horsepower.

Awesome Full Featured Resource!

I've had this app since it was two separate sections relating to ET speed and estimated HP. The developer has continually added new, abstract, unusual and very useful information modules. The newest update seems to include programming info for computerized CNC machines.

Too complicated!

This app is way to complicated, and not accurate at all in my experience.
