What does femtogram per liter measure?

It measures ultralow mass concentrations, equal to 10^-15 grams of substance per liter of volume, often for ultratrace environmental or biological samples.

Why convert fg/L to µg/L?

Converting to microgram per liter, a more common trace concentration unit, helps simplify data interpretation and reporting across environmental and clinical studies.

Is the conversion factor between fg/L and µg/L fixed?

Yes, the conversion factor is 1 femtogram per liter equals 1e-9 microgram per liter, enabling direct linear scaling.
