What is a pennyweight used for?

Pennyweight is traditionally used to measure small amounts of precious metals and gemstones, commonly in gold and silver trading and jewelry making.

Does this tool convert to troy ounces or avoirdupois ounces?

The conversion is based on the troy pennyweight relative to ounces. Care should be taken to distinguish which ounce variant applies, as troy ounces differ in mass from avoirdupois ounces.

Why is it important to distinguish between troy and avoirdupois ounces?

Because troy and avoirdupois ounces have different masses, mixing them without clarification can result in inaccurate weight calculations and valuation errors.
