Questions
Which horsepower do Indian car brochures use?
Most quote PS (metric horsepower, 735.5 W) or bhp. Mechanical/imperial HP is 745.7 W, so 100 PS ≈ 98.6 hp ≈ 73.5 kW.
What does a 1.5 ton AC mean?
‘Ton’ is cooling capacity, not weight: 1 ton of refrigeration = 12,000 BTU/h ≈ 3.517 kW. A 1.5 ton AC removes about 5.3 kW of heat but typically draws only about 1.3–1.8 kW of electricity.
How do I convert kW to HP?
Multiply kW by 1.341 for mechanical HP or by 1.36 for metric HP (PS).
