Units explained
Hectogram
A hectogram (hg) equals 0.1 kilogram, or 100 grams.
From the SI prefix 'hecto-' (from Greek 'hekaton', hundred).
Common in continental European food retail, especially Italy ('etto').
The hecto- prefix dates to the original metric system of 1795.
Electron Mass (rest)
The electron rest mass is about 9.109E-31 kg.
The mass of the electron, the lightest charged elementary particle.
Atomic and particle physics.
Quantified after J. J. Thomson identified the electron in 1897.
Hectogram to Electron Mass (rest) conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between hectograms and electron mass (rest):
To convert hectograms to electron mass (rest), multiply the value in hectograms by 1.097768e+29. To reverse, multiply electron mass (rest) by 9.10939e-30.
