Facts about the Kilogram
The kilogram is the SI base unit of mass, defined by taking the fixed numerical value of Planck’s constant (h) as 6.62607015×10⁻³⁴ J·s.
The kilogram was initially defined as the mass of one liter of water. Later, it was physically represented by a platinum-iridium cylinder stored in France. In 2019, it was redefined in terms of fundamental constants of physics, making it more stable and universally applicable.
Kilograms are used globally for weighing people, luggage, industrial goods, grocery items, and shipping cargo. It’s the most widely recognized mass unit across both scientific and everyday contexts.

Facts about the Ounce
The ounce is a unit of mass in the imperial system, commonly used in the U.S. and U.K., equal to approximately 28.3495 grams.
Historically, the ounce varied in value depending on region and use (troy, apothecaries, or avoirdupois). The common avoirdupois ounce, now standardized, remains in wide use.
Used to measure small quantities such as food portions, spices, snacks, and precious metals like gold and silver (although these use the troy ounce).
