Mg to Grams Calculator
What is a Milligram (mg)?
A milligram (mg) is a unit of mass in the metric system equal to one-thousandth (1/1000) of a gram. It is commonly used to measure small quantities such as medication dosages, vitamins, food additives, or chemical substances.
1 milligram = 0.001 grams
What is a Gram (g)?
A gram (g) is a standard metric unit used to measure mass or weight. It is widely used in laboratories, recipes, and industrial applications. When you convert milligrams to grams, you’re essentially dividing the milligram value by 1000.
Formula to Convert Milligrams to Grams
The conversion formula is simple: Grams=Milligrams1000\text{Grams} = \frac{\text{Milligrams}}{1000}Grams=1000Milligrams
Example:
If you have 2500 mg, then: 2500÷1000=2.5 grams2500 ÷ 1000 = 2.5 \text{ grams}2500÷1000=2.5 grams
So, 2500 mg = 2.5 g
