How to Convert Megagram to Femtogram
To convert Mg to kg: multiply by 1,000. To convert Mg to short tons: multiply by 1.10231.
1 Mg = 1,000 kg = 10⁶ g = 1 tonne = 2,204.62 lb.
For example, 1 Megagram (Mg) = 1.000000e+21 Femtogram (fg).

About Megagram (Mg)
Definition
The megagram is equal to 1,000 kilograms or one million grams — equivalent to one metric ton (tonne).
Mathematical Relationship
1 Mg = 1,000 kg = 10⁶ g = 1 tonne = 2,204.62 lb.
Conversion Formula
To convert Mg to kg: multiply by 1,000. To convert Mg to short tons: multiply by 1.10231.
Practical Applications
Vehicle weights, cargo shipping, bulk commodities, and industrial material quantities.
Interesting Facts
A small car weighs about 1–1.5 Mg. An adult elephant weighs about 5–6 Mg.
Common Mistakes
Case sensitivity: Mg (megagram) vs. mg (milligram) differ by 10⁹! Always check capitalization.
Educational Tips
1 Mg = 1 tonne = 1,000 kg. Think of a small car's weight as an anchor for this unit.
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.
