What is a femtogram used to measure?

A femtogram measures extremely small masses such as viruses, biomolecules, nanoparticles, and ultrafine aerosol particles.

How many micrograms are in one femtogram?

One femtogram equals one billionth (1×10⁻⁹) of a microgram.

Why convert femtograms to micrograms?

Converting to micrograms helps express tiny mass measurements in more standard and practical units for laboratory and environmental analyses.
