How many milligrams are in 1 gram?

One gram is equal to 1,000 milligrams because of the metric system's base-10 structure, where the prefix 'milli-' denotes a factor of one-thousandth. Therefore, to convert grams to milligrams, you multiply the number of grams by 1,000. This means that 1 gram = 1,000 milligrams. Understanding this metric conversion is fundamental in pharmacy and medicine, where precise measurements of medications and doses are critical for patient safety.
