Accurate conversion between milligrams (mg) and grams (g). Perfect for cooking, pharmacy, chemistry, and scientific measurements.
Conversion Factor
1 gram (g) = 1000 milligrams (mg)
Precision: 4 Decimal Places | Formula: g = mg ÷ 1000
Understanding these metric weight units and their practical applications.
1 gram (g) = 1000 milligrams (mg)
g = mg ÷ 1000
mg = g × 1000
Convert 750 milligrams to grams:
g = mg ÷ 1000
g = 750 mg ÷ 1000
g = 0.75
g = 0.7500 (with 4 decimal places)
This conversion is exact since both units are part of the metric system, which uses powers of 10.
A metric unit of mass equal to one thousandth of a gram (0.001 g) or one millionth of a kilogram (0.000001 kg).
Common uses:
A metric unit of mass equal to one thousandth of a kilogram (0.001 kg) or 1 cubic centimeter of water's mass at 4°C.
Common uses:
| Unit | Abbreviation | Equivalent in grams | Equivalent in milligrams |
|---|---|---|---|
| Kilogram | kg | 1000 g | 1,000,000 mg |
| Gram | g | 1 g | 1000 mg |
| Milligram | mg | 0.001 g | 1 mg |
| Microgram | µg | 0.000001 g | 0.001 mg |
Common questions about milligrams, grams, and their conversion.
There are exactly 1000 milligrams (mg) in one gram (g). This is an exact conversion within the metric system, which is based on powers of 10.
This relationship makes conversions between these units straightforward—simply multiply by 1000 when converting grams to milligrams, or divide by 1000 when converting milligrams to grams.
The choice between milligrams and grams depends on the size of the mass being measured:
As a general rule, use grams for masses larger than 1 gram, and milligrams for masses smaller than 1 gram.
Precision is particularly important in several contexts:
In many cases, especially with medications, the difference between a therapeutic dose and a harmful dose can be just a few milligrams.
Milligrams and grams are part of the metric system's decimal-based hierarchy for mass:
1 kilogram (kg) = 1000 grams (g)
1 gram (g) = 1000 milligrams (mg)
1 milligram (mg) = 1000 micrograms (µg)
This consistent pattern of multiplying or dividing by 1000 makes converting between metric mass units straightforward. Each unit is 1000 times larger than the one below it in the hierarchy.
For example, to convert kilograms to milligrams, you would multiply by 1,000,000 (1000 × 1000).
For reference, here are some common conversions between metric and imperial weight units:
1 gram (g) ≈ 0.035274 ounces (oz)
1 ounce (oz) ≈ 28.3495 grams (g)
1 pound (lb) ≈ 453.592 grams (g)
1 kilogram (kg) ≈ 2.20462 pounds (lb)
While the metric system (using grams and milligrams) is standard in science, medicine, and most countries worldwide, imperial units (ounces, pounds) are still used in the United States and a few other countries for everyday measurements.
