To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
For example, 1 Petagram (Pg) = 1.000000e+27 Picogram (pg).
| Petagram (Pg) | Picogram (pg) |
|---|---|
| 0.1 | 1.000000e+26 |
| 0.5 | 5.000000e+26 |
| 1 | 1.000000e+27 |
| 2 | 2.000000e+27 |
| 5 | 5.000000e+27 |
| 10 | 1.000000e+28 |
| 25 | 2.500000e+28 |
| 50 | 5.000000e+28 |
| 100 | 1.000000e+29 |
| 500 | 5.000000e+29 |
| 1000 | 1.000000e+30 |
The petagram equals 10¹⁵ grams or one billion tonnes (one gigatonne).
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
Global carbon budgets: about 10 Pg of carbon are emitted annually from fossil fuels.
The total mass of all life on Earth is estimated at about 550 Pg of carbon.
Confusing Pg (petagram = 10¹⁵ g) with PB (petabyte). In mass contexts, P = peta = 10¹⁵.
1 Pg C = 1 gigatonne of carbon. Annual human CO₂ emissions are about 10 Pg C — a key climate figure.
The picogram is a unit of mass equal to 10⁻¹² grams or 10⁻¹⁵ kilograms — one trillionth of a gram.
1 pg = 10⁻¹² g = 10⁻¹⁵ kg = 1,000 fg. A human cell contains about 6 pg of DNA.
To convert pg to grams: multiply by 10⁻¹². To convert pg to ng: divide by 1,000.
Quantifying DNA in cells (~6 pg per human cell), measuring blood hormone levels, and forensic trace analysis.
The total DNA in a single human cell weighs about 6.4 pg — this tiny amount contains your entire genetic blueprint.
Confusing pg (picogram) with pg as an abbreviation for 'page'. Context matters in mixed documents.
Remember: each human cell has ~6 pg of DNA. This anchors the picogram in biology.
