How to Convert Hectogram to Femtogram
To convert hg to grams: multiply by 100. To convert hg to kg: divide by 10.
1 hg = 100 g = 0.1 kg = 10 dag = 3.527 oz.
For example, 1 Hectogram (hg) = 1.000000e+17 Femtogram (fg).

About Hectogram (hg)
Definition
The hectogram is a unit of mass equal to 100 grams or one tenth of a kilogram.
Mathematical Relationship
1 hg = 100 g = 0.1 kg = 10 dag = 3.527 oz.
Conversion Formula
To convert hg to grams: multiply by 100. To convert hg to kg: divide by 10.
Practical Applications
Italian food shopping (un etto di prosciutto = 100 g of ham). Occasionally in European nutrition contexts.
Interesting Facts
In Italy, 'un etto' (one hectogram = 100 g) is the standard portion unit at deli counters.
Common Mistakes
Rarely encountered outside Italy, so people may not recognize it. 1 hg = 100 g = 0.1 kg.
Educational Tips
In Italy, 'un etto' = 100 g. The 'per 100 g' column on nutrition labels is essentially 'per hectogram'.
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.
