How many milligrams are in 1 gram?

To determine how many milligrams are in 1 gram, it's important to understand the metric conversions between these two units of measurement.

In the metric system, the prefix "milli-" denotes a factor of one-thousandth (1/1000). Therefore, 1 gram (g) is equivalent to 1000 milligrams (mg). This means that when converting grams to milligrams, you multiply the number of grams by 1000.

Thus, if you have 1 gram and you want to express it in milligrams, you perform the following calculation:

1 g × 1000 mg/g = 1000 mg.

That’s why the correct answer is 1000 milligrams in 1 gram. Understanding these metric prefixes is fundamental for accurate calculations in pharmacy and other scientific fields.
