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) = 0.001 Picogram (pg).

The femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
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.
