Examples

Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).

Common mistakes

  • Confusing mass (lb) with force (lbf) in engineering contexts.
  • Mixing metric tonnes (t) with short/long tons.

About Mass

Mass quantifies the amount of matter. The kilogram is defined by Planck’s constant, which anchors mass to fundamental physics. In practice, grams and pounds dominate everyday use—from recipes and parcels to body weight—while tonnes and long tons appear in logistics and industry.

About Kilogram (kg)

Kilogram (kg)

SI base unit of mass defined by fixing Planck’s constant h. The definition anchors mass to quantum physics rather than an artifact. Used universally from commerce to high-precision science.

History: In 2019 the kilogram was redefined via h and the second; before that it referenced the International Prototype of the Kilogram (IPK) stored near Paris.

About Slug

Slug

Imperial engineering unit of mass so that F=ma works with lb·ft·s units. 1 slug ≈ 14.5939 kg; convenient in dynamics calculations.

History: Coined for coherent imperial unit systems. Remains in textbooks and some aerospace/defense engineering analyses.
