Units explained
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
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 to Teragram conversion formula
The relationship between exagrams and teragrams:
To convert exagrams to teragrams, multiply the value in exagrams by 1000000. To reverse, multiply teragrams by 1e-6.
How to use this converter
Type a value into the calculator. The result in teragrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Teragram to Exagram converter for the reverse direction.
Step-by-step: convert exagrams to teragrams
- Write down the value in exagrams (Eg).
- Multiply that value by the factor 1000000.
- The product is the equivalent value in teragrams (Tg).
- To reverse, multiply the teragram value by 1e-6.
Worked examples
Example 1 — Convert 1 Eg to Tg:
1 × 1000000 = 1000000 Tg
Example 2 — Convert 100 Eg to Tg:
100 × 1000000 = 1e+8 Tg
