It's about 350,000,000,000 times as long as a Glucose Molecule.
In other words, the length of a Glucose Molecule is 0.00000000000300 times 0.50 kilometers.(C6H12O6, a.k.a. grape sugar) (open chain form)
Am individual glucose molecule measures 0.00000000000150 kilometers in its open-chain form. Glucose is the most common fuel source of energy in human biology, with 3.75 kilocalories of energy per gram.
It's about 250,000,000 times as long as a Mitochondrion.
In other words, 0.50 kilometers is 266,000,000 times the length of a Mitochondrion, and the length of a Mitochondrion is 0.000000003760 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 250,000,000 times as long as an E. coli Bacterium.
It's about 85,000,000 times as long as a Nucleus (Cellular).
In other words, the length of a Nucleus (Cellular) is 0.0000000120 times 0.50 kilometers.(for animal cell)
The nucleus of an animal cell measures an average of 0.00000000600 kilometers. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
It's about 65,000,000 times as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 0.0000000150 times 0.50 kilometers.(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.
