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) = 5309175517 Muon Mass (mμ).

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 muon mass is the rest mass of the muon particle, approximately 1.884 × 10⁻²⁸ kilograms or about 207 times the electron mass.
mμ ≈ 206.77 × mₑ ≈ 0.1126 × mₚ (proton mass) = 105.66 MeV/c².
To convert muon masses to kg: multiply by 1.883531627 × 10⁻²⁸.
Muon tomography (imaging volcanoes, pyramids), muon-catalyzed fusion, and cosmic ray detection.
The muon's discovery prompted physicist I.I. Rabi to quip 'Who ordered that?' — it was completely unexpected.
Muons are not mesons — they're leptons (like electrons), not quark-antiquark pairs.
Think of a muon as a 'fat electron' — same charge, same spin, but 207× heavier. It decays in about 2.2 microseconds.
