What does one joule represent?

One joule is the SI derived unit of energy, defined as the energy transferred when a force of one newton moves an object one meter.

When should I use pound-force inch units?

Pound-force inch units are used primarily in US customary contexts to quantify small mechanical work, such as torque in inch-based systems and energy delivered by small actuators.

Is pound-force inch an SI unit?

No, pound-force inch is not an SI unit and is mainly used in US customary mechanical measurements.
