One long ton equals exactly 32,150.747 pennyweights. This precise conversion comes from the relationship: 1 long ton = 2,240 pounds = 26,880 troy ounces = 32,150.747 pennyweights (since 1 troy ounce = 20 pennyweights).

Pennyweights provide practical precision for precious metal valuation because they're small enough to represent individual pieces yet large enough to avoid unwieldy decimals. One pennyweight of gold represents meaningful monetary value, making pricing transparent. The troy ounce system (including pennyweights) has been used for precious metals for centuries, creating standardized pricing across global markets. Traders continue using pennyweights because they maintain consistency with centuries of established price benchmarks.
