Full Description
Power ratings pop up in multiple disciplines. Mechanical specs cite horsepower, HVAC engineers reference BTU per hour or tons, while electricians prefer watts and kilowatts. This converter keeps the math consistent across the board.
It relies on exact conversion factors so you can trust the results for procurement, sizing generators, or comparing appliance efficiency.
Pair it with the RMS calculator for electrical design, or the natural gas converter when analyzing HVAC loads.
Frequently Asked Questions
Does it include metric horsepower?
It currently uses mechanical horsepower (745.699872 W). Add more entries to the power units list if you need metric or boiler horsepower.
What about cooling tons?
Tons of refrigeration are included. They’re commonly used to describe air conditioning capacity.
Can I convert BTU/h to kW directly?
Yes. Choose BTU/h as the source unit and kilowatts as the target unit to get the exact conversion.
Are decimals rounded?
Results display with unit-specific precision but retain full accuracy internally, so copying the numbers preserves precision.
