To convert grams to milligrams, you need to know that 1 gram is equal to 1,000 milligrams. Therefore, to find out how many milligrams are in 9 grams, you simply multiply 9 by 1,000.
So, the calculation is as follows:
9 grams × 1,000 = 9,000 milligrams
This means that 9 grams is equal to 9,000 milligrams. Conversions like these are useful in many situations, such as cooking, pharmaceuticals, or when dealing with measurements in scientific contexts.
