What does femtogram (fg) measure?

A femtogram is a unit of mass equal to 10^-15 grams, used to express very small masses at micro- and nano-scales.

What is a megagram (Mg)?

A megagram is an SI-derived unit of mass equal to 1,000,000 grams or 1,000 kilograms, equivalent to a metric tonne.

Why convert from femtogram to megagram?

Converting between these units bridges scales from extremely small nanoscale masses to large industrial mass quantities, enabling cross-disciplinary comparisons.
