 It's about 4,500,000,000,000,000 times as wide as a Glucose Molecule In other words, 6,400 kilometers is 4,300,000,000,000,000.00000000000000000 times the width of a Glucose Molecule, and the width of a Glucose Molecule is 0.00000000000000023 times that amount. (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 3,500,000,000,000 times as long as a Mitochondrion In other words, 6,400 kilometers is 3,400,000,000,000 times the length of a Mitochondrion, and the length of a Mitochondrion is 0.000000000000294 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 3,000,000,000,000 times as long as a Bacterium In other words, 6,400 kilometers is 3,200,000,000,000 times the length of a Bacterium, and the length of a Bacterium is 0.00000000000031 times that amount. (Escherichia coli) (rod-shaped configuration)An rod-shaped E. coli bacterium measures about 0.00000000200 kilometers in length. A staple of biology labs, E. coli can reproduce in as little as twenty minutes. It's about 1,000,000,000,000 times as long as a Cell's Nucleus In other words, 6,400 kilometers is 1,100,000,000,000 times the length of a Cell's Nucleus, and the length of a Cell's Nucleus is 0.00000000000091 times that amount. (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 850,000,000,000 times as long as a Red Blood Cell In other words, 6,400 kilometers is 850,000,000,000 times the length of a Red Blood Cell, and the length of a Red Blood Cell is 0.0000000000012 times that amount. (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 65,000,000,000 times as wide as a Strand of Hair In other words, 6,400 kilometers is 65,000,000,000 times the width of a Strand of Hair, and the width of a Strand of Hair is 0.000000000015 times that amount. (average)A strand of human hair averages 99 µm (micrometers), with blond hair being the finest and black hair the thickest. On a healthy scalp, each strand of hair will last up to 6 years. It's about 60,000,000,000 times as tall as a sheet of Paper In other words, 6,400 kilometers is 60,000,000,000 times the height of a sheet of Paper, and the height of a sheet of Paper is 0.000000000020 times that amount. (for US Letter, a.k.a. ANSI A; 215.9mm by 279.4mm (8.5 in x 11 in); 20lb)A single sheet of 20 lb, 8.5 inch x 11 inch paper is just 0.0000001000 kilometers thick. This style of paper weighs a mere 5 g per sheet.
