What is a quarter (US) in terms of pounds?

A quarter (US) is a unit of mass equal to 25 pounds, which is one quarter of a US hundredweight.

Why convert from quarter (US) to electron mass (rest)?

Such conversions help bridge macroscopic mass measurements with fundamental particle masses, useful in theoretical physics and scientific research.

Is this conversion practical for everyday weight measurements?

No, due to the extremely small size of the electron mass, resulting values are very large and mainly suitable for specialized scientific applications.
