Convert Teragram to Exagram
Convert teragrams to exagrams instantly. 1 teragram = 1e-6 exagram — use the live calculator, the exact formula, a conversion table and worked examples. Also check the Exagram to Teragram converter for the reverse conversion.
Units explained
Teragram
A teragram (Tg) equals 10^9 kilograms, or one million metric tons.
From the SI prefix 'tera-' (from Greek 'teras', monster).
Used in large-scale environmental and industrial mass accounting.
The tera- prefix entered the SI in 1960.
Exagram
An exagram (Eg) equals 10^15 kilograms, or one quintillion grams.
From the SI prefix 'exa-' (from Greek 'hex', six, denoting the sixth power of 1000).
Confined to planetary- and atmospheric-scale mass discussions; never used in daily measurement.
The exa- prefix was adopted by the General Conference on Weights and Measures (CGPM) in 1975.
Teragram to Exagram conversion formula
The relationship between teragrams and exagrams:
To convert teragrams to exagrams, multiply the value in teragrams by 1e-6. To reverse, multiply exagrams by 1000000.
How to use this converter
Type a value into the calculator. The result in exagrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Exagram to Teragram converter for the reverse direction.
Step-by-step: convert teragrams to exagrams
- Write down the value in teragrams (Tg).
- Multiply that value by the factor 1e-6.
- The product is the equivalent value in exagrams (Eg).
- To reverse, multiply the exagram value by 1000000.
Worked examples
Example 1 — Convert 1 Tg to Eg:
1 × 1e-6 = 1e-6 Eg
Example 2 — Convert 100 Tg to Eg:
100 × 1e-6 = 1e-4 Eg
