It's about one-and-a-half times as long as an E. coli Bacterium.
It's about one-and-three-fifths times as long as a Mitochondrion.
In other words, the length of a Mitochondrion is 0.625 times 3 microns.(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 half as long as a Nucleus (Cellular).
In other words, the length of a Nucleus (Cellular) is 2 times 3 microns.(for animal cell)
The nucleus of an animal cell measures an average of six micrometers. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
It's about two-fifths as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 2.5 times 3 microns.(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.
