History

Newton (N)

In 1948, the General Conference on Weights and Measures designated the newton as the SI unit for measuring force, naming it in recognition of Sir Isaac Newton’s contributions to physics. Defined as the force needed to accelerate a 1-kilogram mass by 1 meter per second squared, the newton connects directly to the basic SI units for mass, distance, and time. It is the standard unit for quantifying force, weight, and pressure in scientific and engineering fields. This clear definition supports consistent international measurement and highlights the newton’s foundational role in science and technology.

Pound-force (lbf)

The pound-force (lbf) is in the imperial system. It is the force gravity exerts on one pound of mass. Today, it is standardized to 4.44822 newtons. Pound-force has long been used in engineering, aviation, and the U.S. military. Despite the shift to metric, the pound-force (lbf) is still important in places that use imperial units. It is used in aerospace, engine performance, and mechanical testing. Its use demonstrates the enduring impact of imperial units.
