The Three Parts of a Measurement

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Every measurement carries three parts: a number giving magnitude, a unit giving the standard of comparison, and implied uncertainty.

Show

Reporting a dose as "100 mg" states a magnitude and unit; the number alone could read as ten times intended.

Watch for

Dropping the unit is not a shortcut — a bare number can be dangerously ambiguous, as with a dose in milligrams or grams.
