Questions about this tool
How many foot-pounds-force per second are in one watt?
1 W = 0.737562 ft·lbf/s exactly.
How do I convert watts to foot-pounds-force per second?
Use ft·lbf/s = W × 0.7375621493. For example, 25 W = 18.4391 ft·lbf/s.
How many watts are in one foot-pound-force per second?
1 ft·lbf/s = 1.35582 W.
What is the difference between mechanical and metric horsepower?
Mechanical horsepower is about 745.7 watts and is used in the US, while metric horsepower (PS) is 735.5 watts and is used in Europe and Japan. The same engine therefore shows a PS figure about 1.4% higher.
How many kilowatts is one ton of refrigeration?
One ton of refrigeration is 12000 BTU per hour, about 3.517 kW of cooling capacity. That is cooling output, not electricity use; the unit draws less power depending on its efficiency.
