Examples

1. Converting Electric Motor Specifications

Electrical Engineer
Background
An engineer is reviewing a mechanical pump rated at 1.5 horsepower and needs to determine its electrical power consumption in watts to size the circuit breaker.
Problem
The engineer needs the exact wattage equivalent of 1.5 hp rounded to 4 decimal places.
How to Use
Enter 1.5 in the horsepower field and set the decimal precision to 4.
Example Config
horsepower: 1.5, precision: 4
Outcome
The tool outputs a JSON result showing 1118.5498 watts.

2. High-Precision Generator Sizing

Industrial Facility Manager
Background
A facility manager needs to convert a 50 horsepower backup generator's mechanical output to watts with high precision for load balancing.
Problem
Convert 50 hp to watts with a precision of 6 decimal places.
How to Use
Input 50 in the horsepower field and set the precision parameter to 6.
Example Config
horsepower: 50, precision: 6
Outcome
The tool calculates the power output as 37284.993579 watts.
