1 E11 kg (original) (raw)

To help compare different orders of magnitude we list here masses between 1011 kilograms (100 megatonnes) and 1012 kilograms (1 gigatonne). See also masses of other orders of magnitude.

Lighter masses
450 million tonnes: mass of world's human population (assuming 70 kg/person, population between 6 and 6.5 × 109, this is correct to one significant digit - and malnutrition etc would not affect that degree of accuracy)
100-800 million tonnes: estimated biomass of Antarctic krill, Euphausia superba, thought to be the most plentiful creature on the planet
Heavier masses
