What is a grain (gr) in terms of mass?

A grain is a traditional unit of mass equal to exactly 64.79891 milligrams, defined as 1/7000 of an avoirdupois pound.

What does the US hundredweight represent?

The US hundredweight is a unit of mass equal to 100 avoirdupois pounds, commonly used in commercial bulk weight measurements.

Why should I be careful converting between grains and hundredweight?

Because the units differ greatly in scale, conversions of very small grain amounts can lose precision, and the US hundredweight differs from the British hundredweight.
