How to Convert Grams to Milligrams
- 1). Determine the number of grams you want to convert. For example, you might need to know how many milligrams are in a bag of sugar that weighs 50 grams.
- 2). Multiply the number of grams times 1,000. You use the number 1,000 because 1,000 milligrams make up 1 gram.
- 3). Find the product of your multiplication. 50 times 1,000 equals 50,000. Therefore, 50 grams is equal to 50,000 milligrams.
