What does 11 Stone represent?

11 stone (69.85 kg, or 154 lb) is a frequent entry on UK adult-male NHS records for an average-height man and one of the most-searched UK weight conversions because it sits almost exactly at the 70 kg international pharmacological reference body. Converted to metric the figure is 69.85 kg, just 150 g shy of the canonical 70 kg "reference adult" used in weight-based drug dosing tables. The 0.15 kg gap is small enough that British clinicians treat 11 st as a quick proxy for 70 kg when scaling fixed-dose intravenous drugs against weight-banded protocols, with the precise kg figure recorded on the chart for documentation.
