A gram is equivalent to 1000 milligrams. This means that if you have 1 gram of a substance, you can consider that it is made up of 1000 milligrams of the same substance.
The conversion between grams and milligrams is straightforward, based on the metric system, where the prefix ‘milli-‘ means one thousandth. Therefore, for every gram, there are 1000 milligrams. This is useful in many fields, such as cooking, medicine, and scientific research, where precise measurements are often required.
