• 100 pm = 1 Ångström
• 100 pm — covalent radius of sulfur atom^[1]
• 120 pm = van der Waals radius of a neutral hydrogen atom^[2]
• 126 pm — covalent radius of ruthenium atom
• 135 pm — covalent radius of technetium atom
• 153 pm — covalent radius of silver atom
• 154 pm — mode length of (C-C) covalent bond
• 155 pm — covalent radius of zirconium atom
• 175 pm — covalent radius of thulium atom
• 200 pm — highest resolution of a typical electron microscope^[3]
