تحويل الجنيهات إلى الحجر: الصحة واللياقة البدنية وإدارة الوزن

One stone equals exactly 14 pounds. This precise relationship means converting is straightforward: multiply stones by 14 to get pounds, or divide pounds by 14 to get stones. For example, 10 stone equals 140 pounds exactly, and 200 pounds equals 14.29 stone (14 stone 4 pounds). This exact ratio has been standardized internationally and is used consistently in medical, fitness, and commercial applications.

The stone unit developed in medieval Britain as a practical measure for commerce and agriculture, and it remained embedded in British culture and law even after the metric system was adopted for most scientific and commercial purposes. The United States, never fully adopting the metric system, standardized on pounds for all weight measurements. Today, the stone persists in the UK and Ireland primarily for personal health and fitness contexts, while professional and scientific measurements use kilograms.
