What is a pound [lbs] in terms of mass?

A pound [lbs] is a unit of mass in the avoirdupois system, defined exactly as 0.45359237 kilograms.

Why use slugs instead of pounds in some calculations?

Slugs relate mass directly to force and acceleration in US customary units, which is important for dynamics and engineering calculations.

Can I use this conversion for everyday measurements?

No, the slug is mainly used in specialized engineering fields and is not intended for everyday mass measurements.
