Conversion Formula
The formula to convert grams (g) to milligrams (mg) is:
mg = g × 1000
This works because 1 gram is exactly 1000 milligrams. So, to find how many milligrams are in any given number of grams, you multiply by 1000.
Example:
- Given: 0.10 g
- Multiply: 0.10 × 1000 = 100
- Result: 0.10 g equals 100 mg
Conversion Example
- Example 1: Convert 2.5 g to mg
- Start with 2.5 grams
- Multiply by 1000: 2.5 × 1000 = 2500
- Answer: 2.5 g equals 2500 mg
- Example 2: Convert 0.75 g to mg
- Start with 0.75 grams
- Multiply by 1000: 0.75 × 1000 = 750
- Answer: 0.75 g equals 750 mg
- Example 3: Convert 10 g to mg
- Start with 10 grams
- Multiply by 1000: 10 × 1000 = 10000
- Answer: 10 g equals 10000 mg

Conversion Definitions
g (gram): The gram is a metric unit for mass, equal to one thousandth of a kilogram. It is commonly used for measuring small quantities of substances like food, medicine, or chemicals. The gram is widely accepted internationally as a base measurement unit for weight.
mg (milligram): The milligram is a smaller metric unit of mass, equal to one thousandth of a gram. It is used to measure very small weights, such as in pharmaceuticals or nutritional information. Milligrams help express tiny amounts with precision and clarity.
Conversion FAQs
Why do we multiply grams by 1000 to get milligrams?
Because the metric system is based on powers of ten, 1 gram equals 1000 milligrams. Multiplying by 1000 shifts the decimal point three places to the right, converting grams into the smaller unit of milligrams.
Can I convert milligrams back to grams using the same method?
No, to convert milligrams to grams, you divide by 1000 because milligrams are smaller than grams. So if you have 500 mg, dividing by 1000 gives 0.5 g.
Does the conversion change for negative values?
No, negative values represent quantities below zero mass in calculations, so the conversion factor stays consistent. For example, -0.10 g equals -100 mg, using the same multiplication.
Is 0.10 g a precise measurement or an approximation?
It depends on the measuring device and context. 0.10 g may represent an exact value or a rounded one, so precision depends on the scale accuracy used to measure the grams.
Why are grams and milligrams used instead of other units?
Grams and milligrams are convenient for small to moderate masses, especially in science and medicine. Larger units like kilograms or pounds are less practical for tiny amounts, while these metric units fit well within the decimal system.
