1 E-10 m

To help compare different orders of magnitude this page lists lengths between 100 pm and 1 nm (10^-10 m and 10^-9 m). See also lengths of other orders of magnitude.

• Lengths shorter than 100 pm
• 100 pm = 1 Ångström
• 100 pm (0.1 nm) -- covalent radius of sulfur atom
• 126 pm (0.126 nm) -- covalent radius of ruthenium atom
• 135 pm (0.135 nm) -- covalent radius of technetium atom
• 153 pm (0.153 nm) -- covalent radius of silver atom
• 154 pm (0.154 nm) -- length of a typical covalent bond (C-C).
• 155 pm (0.155 nm) -- covalent radius of zirconium atom
• 175 pm (0.175 nm) -- covalent radius of thulium atom
• 225 pm (0.225 nm) -- covalent radius of caesium atom
• 500 pm (0.50 nm) -- width of protein α helix
• Lengths longer than 1 nm
