How to Convert Femtogram to Teragram
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
For example, 1 Femtogram (fg) = 1.000000e-27 Teragram (Tg).

About Femtogram (fg)
Definition
The femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
Mathematical Relationship
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
Conversion Formula
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Practical Applications
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
Interesting Facts
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Common Mistakes
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
Educational Tips
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
About Teragram (Tg)
Definition
The teragram equals 10¹² grams or one million tonnes (one megatonne).
Mathematical Relationship
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
Conversion Formula
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Practical Applications
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Interesting Facts
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Common Mistakes
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Educational Tips
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
