Understanding Stone Measurements

Why Use Stones?

The stone unit provides a convenient middle ground between pounds and larger units. It's particularly useful for tracking body weight changes, as a stone represents a significant but achievable weight loss or gain goal.

Stones and Pounds Notation

Weight is often expressed as a combination of stones and remaining pounds:

  • 150 lbs = 10 st 10 lbs (10 stones and 10 pounds)
  • 175 lbs = 12 st 7 lbs (12 stones and 7 pounds)
  • 200 lbs = 14 st 4 lbs (14 stones and 4 pounds)

International Context

While stones are primarily used in the UK and Ireland, most other countries use kilograms for body weight. The stone is not part of the metric system and is gradually being replaced by kilograms even in the UK, though it remains popular for personal weight measurement.

Practical Tips

  • Weight Loss Goals: Setting goals in stones (e.g., "lose 2 stone") provides clear, achievable targets
  • Medical Records: UK medical records often use stones and pounds for consistency
  • Scales: Many UK bathroom scales display weight in both stones/pounds and kilograms
  • Conversion: Remember 14 pounds = 1 stone for quick mental calculations
