Foot-Pounds Per Second to Boiler Horsepower Converter
Convert foot-pounds per second (ft·lbf/s) to boiler horsepower (hp(S)) with a transparent specialized power base-unit calculation.
Ready. Your working data stays in this browser.
How it works
The browser multiplies ft·lbf/s by 1.35582 to reach the shared SI reference, then divides by 9809.5 to return hp(S). No value leaves the page.
Practical example
Entering 1 ft·lbf/s returns 0.000138214786516 hp(S); the page also shows the exact factors used for an independent check.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
