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.
Kilogram
The kilogram (kg) is the SI base unit of mass, defined by fixing the Planck constant h at 6.62607015E-34 J s.
From Greek 'khilioi' (thousand) plus 'gramma' (small weight).
The worldwide base unit of mass in science, commerce, and everyday life.
Adopted in 1795; redefined through the Planck constant on 20 May 2019.
Teragram to Kilogram conversion formula
The relationship between teragrams and kilograms:
To convert teragrams to kilograms, multiply the value in teragrams by 1e+9. To reverse, multiply kilograms by 1e-9.
How to use this converter
Type a value into the calculator. The result in kilograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Kilogram to Teragram converter for the reverse direction.
Step-by-step: convert teragrams to kilograms
- Write down the value in teragrams (Tg).
- Multiply that value by the factor 1e+9.
- The product is the equivalent value in kilograms (kg).
- To reverse, multiply the kilogram value by 1e-9.
Worked examples
Example 1 — Convert 1 Tg to kg:
1 × 1e+9 = 1e+9 kg
Example 2 — Convert 100 Tg to kg:
100 × 1e+9 = 1e+11 kg
