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) = 4594671.835 Planck Mass (mₚ).

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 Planck mass is the fundamental natural unit of mass, approximately 2.176 × 10⁻⁸ kg (about 21.76 micrograms).
mₚ = √(ℏc/G) ≈ 2.176 × 10⁻⁸ kg ≈ 21.76 µg ≈ 1.31 × 10¹⁹ proton masses.
To convert Planck masses to kg: multiply by 2.176434 × 10⁻⁸.
No direct practical applications — a Planck mass is roughly the mass of a flea egg, but its significance is theoretical.
Unusually, the Planck mass is macroscopic (~22 µg) — about the mass of a flea egg, a grain of sand, or a small dust mite.
Expecting Planck mass to be extremely small like other Planck units — it's actually macroscopic (~22 µg).
Other Planck units are absurdly small or large, but the Planck mass is surprisingly human-scale: about 20 micrograms.
