The smallest unit of measurement for solid medication form is the microgram. This unit is particularly relevant in pharmacology and medication administration, where precise dosing is critical to ensure efficacy and safety. Micrograms are one-millionth of a gram, allowing for extremely small amounts of medication to be measured and administered, which is especially important for potent medications that may require very low doses.

Using micrograms enables healthcare professionals to deliver accurate doses of medications that have a high therapeutic index or require careful titration. This level of precision helps avoid both underdosing, which can lead to ineffective treatment, and overdosing, which can result in adverse effects.

In contrast, while milligrams and grams are larger units of measurement used for solid medications, they do not provide the same level of specificity required for certain medications. Cubic centimeters are a unit of volume, primarily used for liquid medications, and are not applicable when discussing solid dosage forms.
