                                Medication errors due to confusion between weight and volume units are a significant patient safety concern, with some studies showing high rates of dosage errors. The question, 'Is 5mg and 5ml the same?', highlights a fundamental misunderstanding that can lead to dangerous over- or under-dosing. The simple answer is no; milligrams (mg) measure mass, while milliliters (ml) measure volume, and they are not interchangeable.
