Conversion formula
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.
Unit facts
- Kilogram (kg): The kilogram is the SI base unit of mass; since 2019 defined by fixing Planck’s constant.
- Ounce (oz): An ounce (avoirdupois) is exactly 28.349523125 g. Note: precious metals use the troy ounce (~31.1035 g).
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 Ounce (oz)
Ounce (oz)
Equals 1/16 lb; exactly 28.349523125 g. Used for portions, postage, and precious metals (note: troy ounce differs).
History: Medieval trade used multiple ounces; today the avoirdupois ounce dominates in retail while troy ounce survives in bullion markets.
