It's about 2,500,000,000,000 times as wide as a Glucose Molecule
In other words, the width of a Glucose Molecule is 0.000000000000370 times 4 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 2,000,000,000 times as long as a Mitochondrion
In other words, 4 kilometers is 2,130,000,000 times the length of a Mitochondrion, and the length of a Mitochondrion is 0.0000000004690 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 2,000,000,000 times as long as a Bacterium
It's about 650,000,000 times as long as a Cell's Nucleus
In other words, the length of a Cell's Nucleus is 0.00000000150 times 4 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 550,000,000 times as long as a Red Blood Cell
In other words, the length of a Red Blood Cell is 0.00000000190 times 4 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.
It's about 40,000,000 times as wide as a Strand of Hair
It's about 40,000,000 times as tall as a sheet of Paper
