(medium grain)
Composed mainly of quartz, mica, feldspar, or magnetite, a grain of sand measures an average of 0.00000000000000000004050 parsecs. In 2007, a team of seven in Myrtle Beach created the world's tallest sandcastle, which measured 0.0000000000000004890 parsecs in height.
It's about 2,000 times as long as a Strand of Hair.
In other words, the length of a Strand of Hair is 0.0005 times 0.000000000000000006480 parsecs.
(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 2,000 times as tall as a sheet of Paper.

(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 35,000 times as long as a Nucleus (Cellular).
In other words, the length of a Nucleus (Cellular) is 0.0000300 times 0.000000000000000006480 parsecs.
(for animal cell)
The nucleus of an animal cell measures an average of 0.000000000000000000000190 parsecs. The nucleus is the largest organelle in these cells, accounting for about 10% of the cell's total volume.
