How many milligrams are in 1 gram?

One gram is equal to 1,000 milligrams because the metric system is based on powers of ten, which makes conversions straightforward. In this case, "milli-" denotes a factor of one thousandth (1/1000), so when converting grams to milligrams, you multiply by 1,000. Therefore, 1 gram is 1,000 milligrams. Understanding this conversion is essential in using the metric system effectively, especially in fields such as medicine and science where precision in measurement is crucial.
