It's about 50 times as long as an E. coli Bacterium.
It's about 55 times as long as a Mitochondrion.
In other words, 0.0000000990 kilometers is 52.70 times the length of a Mitochondrion, and the length of a Mitochondrion is 0.019 times that amount.(Eukaryotic; average)
A mitochondrion measures between 0.75 and 3 micrometers (Âµm). The mitochondrion is commonly referred to as the powerhouse of the cell, responsible for the generation of ATP. The size, shape, and distribution of mitochondria varies widely, with human liver cells each having 1,000 to 2,000 mitochondria.
