What is a femtogram used to measure?

A femtogram measures extremely small masses at micro- and nano-scales, such as individual viruses, large biomolecules, or nanoparticles.

Why is the troy pound considered obsolete?

The troy pound is mostly a historical mass unit used in apothecaries and precious-metal measures; today, the troy ounce survives mainly for bullion, while the troy pound is less common.

Can I convert femtograms directly to modern pounds?

This tool specifically converts femtograms to the troy or apothecary pound, a historical unit, rather than modern avoirdupois pounds.
