About these units

Slug (slug)

The slug is a unit of mass in the English engineering system, defined such that a slug accelerated at 1 ft/s² experiences a force of 1 pound-force. Numerically, a slug is about 14.5939 kilograms. The slug resolves confusion between mass and force in imperial units by clearly separating pounds-force (lbf) from pounds-mass (lb). In dynamics problems involving Newton's laws, slugs provide a consistent mass measurement within the imperial framework. Although uncommon outside engineering physics education, the slug plays an important conceptual role in bridging imperial and SI thinking.

Kilogram (kg)

The kilogram is the base unit of mass in the SI system and the only SI unit defined directly by a fundamental constant rather than a physical object. Originally, its definition was tied to a platinum–iridium artifact stored in France—the famous "International Prototype Kilogram." Over time, tiny mass changes in the prototype and its official copies created difficulties for high-precision science. In 2019, the kilogram was redefined using Planck's constant, linking mass to the laws of quantum physics through the Kibble balance. This innovation ensures universality, stability, and reproducibility across the world. The kilogram is central to commerce, science, engineering, and every quantitative field dealing with matter. Its decimal relationships with other metric units (grams, milligrams, tons) make it universally convenient. From groceries to spacecraft mass budgets, the kilogram anchors modern mass measurement.
