It's about one-fifth as long as a Mitochondrion.
In other words, 0.000405 milimeters is 0.215 times the length of a Mitochondrion, and the length of a Mitochondrion is 4.65 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-fifth as long as an E. coli Bacterium.
It's about one-fifteenth as long as a Nucleus (Cellular).
In other words, the length of a Nucleus (Cellular) is 15 times 0.000405 milimeters.(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 one-twentieth as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 19 times 0.000405 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.
