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.
Hectogram
A hectogram (hg) equals 0.1 kilogram, or 100 grams.
From the SI prefix 'hecto-' (from Greek 'hekaton', hundred).
Common in continental European food retail, especially Italy ('etto').
The hecto- prefix dates to the original metric system of 1795.
Teragram to Hectogram conversion formula
The relationship between teragrams and hectograms:
To convert teragrams to hectograms, multiply the value in teragrams by 1e+10. To reverse, multiply hectograms by 1e-10.
How to use this converter
Type a value into the calculator. The result in hectograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Hectogram to Teragram converter for the reverse direction.
Step-by-step: convert teragrams to hectograms
- Write down the value in teragrams (Tg).
- Multiply that value by the factor 1e+10.
- The product is the equivalent value in hectograms (hg).
- To reverse, multiply the hectogram value by 1e-10.
Worked examples
Example 1 — Convert 1 Tg to hg:
1 × 1e+10 = 1e+10 hg
Example 2 — Convert 100 Tg to hg:
100 × 1e+10 = 1e+12 hg
