Questions about this tool
How many megawatts are in one kilowatt?
1 kW = 0.001 MW exactly.
How do I convert kilowatts to megawatts?
Use MW = kW × 0.001. For example, 25 kW = 0.025 MW.
How many kilowatts are in one megawatt?
1 MW = 1,000 kW.
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.
