What is a UK quarter (qr)?

The UK quarter is an old British unit of mass equal to one quarter of a long hundredweight, or 28 avoirdupois pounds, historically used in commerce and agriculture.

Why convert quarter (UK) to pennyweight?

Converting quarter (UK) to pennyweight helps translate traditional British mass units into the troy weight system, which is important for precious metals trade, jewelry making, and historical analysis.

Is pennyweight suitable for all weight ranges?

Pennyweight is suited for measuring small masses, particularly precious metals, and may not be practical for converting very large quantities without additional conversions.
