What is a grain (gr) used to measure?

A grain (gr) is a traditional mass unit used in bullet and propellant weights, archery, and historical pharmaceutical dosages.

Why convert from grain to picogram?

Converting from grain to picogram translates traditional small mass values into ultra-fine measurements required in molecular biology, nanotechnology, and analytical chemistry.

Is the picogram a large or small unit of mass?

The picogram is an extremely small unit of mass, equal to one trillionth of a gram.
