What does 'mg' stand for in measurements?

'Mg' stands for milligram, a metric unit of mass that represents one-thousandth of a gram. This measurement is crucial in veterinary medicine, especially in dosages for medications, as it allows for precise quantification. For instance, many medications prescribed for animals are dosed in milligrams to ensure safety and efficacy. Understanding the significance of milligrams helps in accurately interpreting medication labels, adjusting doses based on an animal's weight, and ensuring appropriate treatment for various conditions. The other choices represent different units of mass that do not accurately match the abbreviation 'mg'.
