What is a grain (gr) used for?

A grain is a traditional unit of mass mostly used to specify bullet weights, arrow weights, and historical pharmaceutical doses.

Why convert grains to micrograms?

Converting grains to micrograms allows translation of traditional mass units into highly precise metric units needed for lab, pharmaceutical, and environmental work.

Is the microgram a common unit in science?

Yes, micrograms are frequently used in pharmaceutical dosing, analytical labs, and environmental monitoring for very small mass measurements.
