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) = 6.022141e+25 Dalton (Da).
| Hectogram (hg) | Dalton (Da) |
|---|---|
| 0.1 | 6.022141e+24 |
| 0.5 | 3.011070e+25 |
| 1 | 6.022141e+25 |
| 2 | 1.204428e+26 |
| 5 | 3.011070e+26 |

The hectogram is a unit of mass equal to 100 grams or one tenth of a kilogram.
1 hg = 100 g = 0.1 kg = 10 dag = 3.527 oz.
To convert hg to grams: multiply by 100. To convert hg to kg: divide by 10.
Italian food shopping (un etto di prosciutto = 100 g of ham). Occasionally in European nutrition contexts.
In Italy, 'un etto' (one hectogram = 100 g) is the standard portion unit at deli counters.
Rarely encountered outside Italy, so people may not recognize it. 1 hg = 100 g = 0.1 kg.
In Italy, 'un etto' = 100 g. The 'per 100 g' column on nutrition labels is essentially 'per hectogram'.
The dalton is a unit of mass equal to one unified atomic mass unit (1/12 of a carbon-12 atom), approximately 1.661 × 10⁻²⁷ kg.
1 Da = 1 u = 1.6605390666 × 10⁻²⁷ kg. Proteins range from ~5 kDa to >1,000 kDa.
To convert Da to kg: multiply by 1.6605390666 × 10⁻²⁷. 1 kDa = 1,000 Da.
Protein molecular weights (hemoglobin ≈ 64.5 kDa), DNA fragment sizing, and antibody characterization.
Titin, the largest known protein, has a molecular weight of about 3,800 kDa (3.8 MDa). The average protein is ~40–50 kDa.
The dalton and u are identical — they're just preferred in different fields (Da in biology, u in chemistry/physics).
If a paper says a protein is '50 kDa,' that's 50,000 atomic mass units — about 50,000 hydrogen atoms' worth of mass.
