How to Convert Milligram to Teragram
To convert mg to grams: divide by 1,000. To convert mg to grains: multiply by 0.01543.
1 mg = 0.001 g = 10⁻⁶ kg = 1,000 µg. There are 1,000 mg in 1 gram.
For example, 1 Milligram (mg) = 1.000000e-15 Teragram (Tg).

| 50 | 5.000000e-14 |
| 100 | 1.000000e-13 |
| 500 | 5.000000e-13 |
| 1000 | 1.000000e-12 |
About Milligram (mg)
Definition
The milligram is a unit of mass equal to one thousandth of a gram (10⁻³ g) or one millionth of a kilogram.
Mathematical Relationship
1 mg = 0.001 g = 10⁻⁶ kg = 1,000 µg. There are 1,000 mg in 1 gram.
Conversion Formula
To convert mg to grams: divide by 1,000. To convert mg to grains: multiply by 0.01543.
Practical Applications
Drug tablets (e.g., aspirin 325 mg), caffeine content (coffee ~95 mg/cup), sodium on food labels, and gemstone weights.
Interesting Facts
A single grain of sand weighs about 1 mg. The lethal dose of pure caffeine is roughly 10,000 mg (10 g) for an average adult.
Common Mistakes
Confusing mg with mL — milligrams measure mass, milliliters measure volume. They're only equal for water (density = 1 g/mL).
Educational Tips
A standard paper clip weighs about 1,000 mg (1 g). Use this to visualize what a milligram fraction looks like.
About Teragram (Tg)
Definition
The teragram equals 10¹² grams or one million tonnes (one megatonne).
Mathematical Relationship
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
Conversion Formula
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Practical Applications
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Interesting Facts
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Common Mistakes
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Educational Tips
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
