Frequently Asked Questions

Q: What's the difference between force and pressure?

A: Force is a push or pull (measured in Newtons or pounds-force), while pressure is force distributed over an area (measured in Pascals or PSI). Pressure = Force / Area.

Q: How do I convert between horsepower and kilowatts?

A: 1 mechanical horsepower (hp) = 745.7 W = 0.7457 kW. Note that metric horsepower (PS) is slightly different: 1 PS = 735.499 W.

Q: What is stress intensity factor used for?

A: Stress intensity factor (K) is used in fracture mechanics to predict crack propagation in materials. It's critical for aerospace, pressure vessels, and structural integrity analysis.

Q: Can I use this for professional engineering work?

A: Yes, the conversions use standard engineering conversion factors. However, always verify critical calculations and follow professional engineering standards and codes.

Q: What's the difference between PSI and KSI?

A: PSI = pounds per square inch, KSI = kips per square inch (1 kip = 1000 pounds). So 1 KSI = 1000 PSI.

Q: Is this tool free?

A: Yes, completely free with no registration required.
