What is a pennyweight used for?

Pennyweight is traditionally used to weigh small quantities of precious metals and gemstones, commonly in jewelry and bullion trade.

Why convert pennyweight to femtogram?

This conversion translates familiar precious metal mass measurements into nanoscale units, allowing for highly detailed mass analysis at micro and nano levels.

Are there any challenges using this converter?

Yes, the large numerical conversion factor can lead to rounding errors, and device precision must be adequate for femtogram-level measurements.
