How many milligrams are in one grain?

One grain is equivalent to approximately 60 milligrams. This conversion is significant in the medical and pharmaceutical fields as various medications and dosages are often expressed in grains rather than milligrams. Therefore, understanding this conversion allows healthcare providers to accurately calculate and administer the correct dosages for medications when they are prescribed in grains. This is particularly relevant in practices where older conventions still apply or when dealing with certain types of medications that utilize this measurement. The other options do not reflect the widely accepted conversion rate from grains to milligrams.
