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.
Picogram
A picogram (pg) equals 10^-15 kilogram.
From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).
Single-cell biology and ultratrace chemical analysis.
The pico- prefix entered the SI in 1960.
Teragram to Picogram conversion formula
The relationship between teragrams and picograms:
To convert teragrams to picograms, multiply the value in teragrams by 1e+24. To reverse, multiply picograms by 1e-24.
How to use this converter
Type a value into the calculator. The result in picograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Picogram to Teragram converter for the reverse direction.
Step-by-step: convert teragrams to picograms
- Write down the value in teragrams (Tg).
- Multiply that value by the factor 1e+24.
- The product is the equivalent value in picograms (pg).
- To reverse, multiply the picogram value by 1e-24.
Worked examples
Example 1 — Convert 1 Tg to pg:
1 × 1e+24 = 1e+24 pg
Example 2 — Convert 100 Tg to pg:
100 × 1e+24 = 1e+26 pg
