Frequently Asked Questions
-
What is a Stone (US)?
-
Stone (US) is a traditional British unit of mass equal to exactly 14 avoirdupois pounds, commonly used historically for body and commodity weights.
-
What does Pound-force square second/foot measure?
-
It is an imperial unit of mass corresponding to the mass that accelerates at 1 ft/s² when acted on by a force of 1 pound-force; it is also known as a slug.
-
Why convert Stone (US) to Pound-force square second/foot?
-
This conversion is useful for engineering and mechanical calculations that express mass through force and acceleration units, especially within the US customary system.
