What is the conversion of one gram (g) to milligrams (mg)?

One gram (g) is equivalent to 1000 milligrams (mg). This relationship is based on the metric system, where the prefix "milli-" denotes a factor of one thousandth. Therefore, since there are 1000 milligrams in one gram, it follows that to convert grams to milligrams, one must multiply the number of grams by 1000.

For example, if you have 1 gram and want to convert it to milligrams, you simply calculate 1 g × 1000 mg/g = 1000 mg. This fundamental understanding is crucial in medication dosage calculations, ensuring accurate conversions for safe and effective patient care.
