What Is This Tool?

This tool allows you to convert force values from the pound foot per square second unit, commonly known as the poundal, into petanewtons [PT], an SI-derived unit for extremely large forces.

How to Use This Tool?

  • Enter the force value in pound foot per square second.
  • Select 'pound foot/square second' as the input unit and 'petanewton [PT]' as the output unit.
  • Click convert to see the equivalent force expressed in petanewtons.

Key Features

  • Supports conversion between the pound foot/square second and petanewton [PT] units.
  • Browser-based and easy to use without any installation.
  • Ideal for translating legacy imperial FPS units into large-scale SI force values.

Examples

  • Converting 100 pound foot/square second gives 1.38254954376e-14 petanewton [PT].
  • Converting 0.5 pound foot/square second results in 6.9127477188e-17 petanewton [PT].

Common Use Cases

  • Solving classroom problems involving FPS force units where pound denotes mass.
  • Analyzing legacy engineering documents using imperial units for force.
  • Comparing small-scale mechanical forces to astronomical or planetary scale forces in geophysics and astrophysics.

Tips & Best Practices

  • Ensure the input force is expressed in pound foot per square second before converting.
  • Use petanewton as the output unit only when dealing with extremely large forces to maintain meaningful results.
  • Cross-check conversions when working between imperial and SI unit systems for accuracy.

Limitations

  • Because the conversion factor is extremely small, results in petanewton will often be tiny numbers unsuitable for everyday force calculations.
  • Petanewtons are practical only for very large force magnitudes, so avoid using this unit for small-scale dynamics to prevent confusion.

Frequently Asked Questions

What is a pound foot per square second?
It is a force unit in the FPS system equal to the force needed to accelerate a 1 lb mass at 1 ft/s², also known as the poundal.

What does petanewton measure?
A petanewton is an SI-derived unit representing extremely large forces, equal to 10^15 newtons, used in planetary and stellar-scale physics.

When should I use petanewton units?
Use petanewtons to express very large forces encountered in astrophysics, geophysics, and planetary sciences rather than small everyday forces.

Key Terminology
