About these units
Stone (st)
The stone equals 14 pounds, or approximately 6.35029 kilograms, and is commonly used in the United Kingdom and Ireland for expressing human body weight. It has deep traditional roots, originating from stones used as counterweights in early commerce. Although largely replaced by metric units in most applications, the stone remains emotionally and culturally significant for personal weight expression in the UK. Many people find it more intuitive and relatable than kilograms due to long-standing social habits. The stone's endurance highlights how measurement systems reflect cultural identity as much as mathematical convenience. It is one of the few units still commonly used in conversation but not in scientific or industrial contexts.
Didrachma (Biblical Greek) (didrachma)
The didrachma, weighing around 8.5–9 grams, represented two drachmas. It appears in Greek, Roman, and biblical texts, often as a common temple tax or civic fee amount. Its moderate size made it practical for everyday transactions, bridging smaller denominations and larger, more valuable coins such as tetradrachms. The didrachma's consistent appearance in multiple cultures shows how interconnected the ancient Mediterranean economies were.
