What is a pound-force inch?

A pound-force inch is a unit of energy representing the work done by a one pound-force acting over a one-inch displacement used in US customary mechanical contexts.

How does the megajoule relate to other energy units?

The megajoule is an SI-derived unit equal to one million joules, commonly used for large-scale energy like fuel content, electrical energy, and industrial processes.

Why do conversion results appear as very small decimal numbers?

Because pound-force inch measures very small energies and megajoule measures very large energies, conversions result in very small decimal values.
