A “small gross” may sound peculiar in the world of measurements, yet it holds a significant niche in the realm of counting. A small gross equals 120 units, serving as a fascinating intermediate between a dozen and a gross. This unit reflects the duodecimal system’s influence, a base-12 number system used historically in trade and counting, particularly before the widespread adoption of the decimal system. While its usage is rarer today, it was once quite practical for merchandise packaging and bulk items, highlighting humanity’s penchant for diverse mathematical solutions in different eras. Rediscovering units like the small gross bridges the gap between historical trade practices and modern numerical systems, shedding light on how societies have quantified goods across centuries.
A “Trio” typically brings to mind a group of three people performing music together, but did you know it also exists as a unit of measurement, albeit an unconventional one? In certain contexts, particularly in gambling and some sports betting, a trio refers to a selection or combination involving three specific items or outcomes. This concept is often used in horse racing, where punters select three horses to finish in the top three positions in any order, placing bets on the “trio.”
The usage of “trio” as a unit doesn’t stop there. In ancient times, the term “trio” was used to count certain items, similar to a pair or dozen. While not as widely recognized or used in modern measurement systems, it highlights the fascinating ways in which numbers and quantities have been grouped according to cultural significance throughout history.
