It's about as long as a Nucleus (Cellular).
(for animal cell)
The nucleus of an animal cell measures an average of 0.006 milimeters. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
It's about four-fifths as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 1.30 times 0.006 milimeters.(a.k.a. RBCs, a.k.a. haematids, a.k.a. erythrocyte, a.k.a. erythroid cells, a.k.a. red blood corpuscles) An average Red Blood Cell measures 7.5 µm (micrometers) in diameter. An average human has 20 - 30 trillion red blood cells in their body and each cell completes a circulatory lap in about 20 seconds.
It's about three times as long as an E. coli Bacterium.
It's about three times as long as a Mitochondrion.
In other words, 0.006 milimeters is 3.190 times the length of a Mitochondrion, and the length of a Mitochondrion is 0.3130 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.
It's about one-fifteenth as long as a Strand of Hair.
It's about one-fifteenth as tall as a Human hair, Strand of.
It's about one-fifteenth as tall as a sheet of Paper.
