30mg

Thirty milligrams (30 mg) is a unit of mass in the metric system equal to 0.03 grams. The milligram (mg) represents one thousandth of a gram. A quantity of 30 mg is equivalent to 30,000 micrograms and to 0.00003 kilograms.

In medicine and pharmacology, mg is the standard unit for dosages and drug concentrations. Medicines sold as tablets, capsules, or liquids specify the amount of active ingredient in mg per unit or per milliliter. Dosing decisions commonly use mg, sometimes expressed as mg per kilogram of body weight.

Some drugs use fixed mg doses, while others require mg/kg calculations. The same mg amount can reflect very different potencies depending on the drug, so a 30 mg dose may be appropriate for one medication and insufficient or excessive for another.

In nutrition and dietary supplements, mg is used to quantify minerals and vitamins per serving, such as calcium or iron. Daily values are often given in mg, and fortification labels may list multiple nutrients in milligrams.

Practical considerations include careful measurement with calibrated devices, as small errors in mg can affect treatment outcomes. Always follow labeling and professional guidance, and be mindful that mg doses are not interchangeable across different substances.
