What is a pound-force inch (lbf·in)?

A pound-force inch is a torque unit representing the moment produced by one pound-force applied perpendicularly at one inch from a pivot.

What does one newton meter (N·m) represent?

One newton meter is the SI torque unit representing the moment from a one newton force applied perpendicularly at one meter from a lever arm.

Why is conversion between lbf·in and N·m important?

Converting between these units allows translation of torque values used in imperial systems into SI units widely adopted in engineering and industry.
