20 cm is 200,000 um (micrometers), which is 200,000,000 nm, or 2 billion angstroms. I would say that a human hand is approximately 20 centimeters in length (the difference of a few cm in either direction doesn't have much of an effect, in this case). It has an electric charge of + 2 / 3 e. It has a mass of 172.76 ± 0.3 gev/c 2, which is close to the rhenium atom mass. Quarks arefundamental particles, and three quarks make up protons andneutrons, which in turn make up atoms. Like all other quarks, the top quark is a fermion with spin 1 / 2 and participates in all four fundamental interactions: Gravitation, electromagnetism, weak interactions, and strong interactions.. 20 cm is 200,000 um (micrometers), which is 200,000,000 nm, or 2 billion angstroms.
