It's about 55,000,000 times as long as a Grain of Sand.
In other words, 71 kilometers is 56,800,000 times the length of a Grain of Sand, and the length of a Grain of Sand is 0.00000001760 times that amount.
(medium grain)
Composed mainly of quartz, mica, feldspar, or magnetite, a grain of sand measures an average of 0.000001250 kilometers. In 2007, a team of seven in Myrtle Beach created the world's tallest sandcastle, which measured 0.0151 kilometers in height.
It's about 700,000,000 times as tall as a sheet of Paper.
In other words, the height of a sheet of Paper is 0.000000001000 times 71 kilometers.
(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.
It's about 700,000,000 times as long as a Strand of Hair.
In other words, 71 kilometers is 720,000,000 times the length of a Strand of Hair, and the length of a Strand of Hair is 0.00000000140 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 9,500,000,000 times as long as a Red Blood Cell.
In other words, the length of a Red Blood Cell is 0.000000000110 times 71 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 10,000,000,000 times as long as a Nucleus (Cellular).
In other words, 71 kilometers is 12,000,000,000 times the length of a Nucleus (Cellular), and the length of a Nucleus (Cellular) is 0.0000000000830 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 35,000,000,000 times as long as an E. coli Bacterium.
In other words, the length of an E. coli Bacterium is 0.0000000000280 times 71 kilometers.
(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.
