How small is a nanometer, really?
Visible light. Violet light is about 4e-7 m and red light about 7e-7 m.
Leading-edge transistor gate. 3 nm is 3e-9 m, or 0.003 µm.
A human hair is about 80,000 nm wide: 80 µm, 0.08 mm, 8e-5 m. That is about 26,667 times wider than a 3 nm transistor.
A DNA double helix is about 2 nm across: 2e-9 m.
Worked examples
Boundary: nm is not Nm
Lowercase nm means nanometer, a unit of length covered by this tool. Capitalized Nm (or N·m) means newton-meter, a unit of torque, which is a completely different quantity handled by our separate newton-meter to foot-pound converter. The two share letters but never share a formula.
Frequently asked questions
There are exactly 1,000,000,000 nanometers in one meter, because 1 nm = 10^-9 m by the exact SI definition of the nano prefix.
Multiply the nanometer value by 10^-9 (divide by 1,000,000,000). For example, 500 nm x 10^-9 = 5e-7 m.
Multiply the meter value by 1,000,000,000 (10^9). For example, 2.5 m x 10^9 = 2.5e9 nm.
1 nm = 0.001 micrometers (µm), because 1 µm = 1,000 nm exactly.
1 nm = 0.000001 millimeters (10^-6 mm), because 1 mm = 1,000,000 nm exactly.
1 nm = 10^-12 kilometers, because 1 km = 1,000,000,000,000 nm exactly.
No. A micrometer is 1,000 times bigger than a nanometer: 1 µm = 1,000 nm exactly.
500 nm = 5e-7 m (0.0000005 m). Multiply 500 by 10^-9.
1 nm = 1,000 picometers (pm) exactly, since pico is 10^-12 and nano is 10^-9.
1 nm = 10 angstroms (Å) exactly, because 1 Å = 0.1 nm.
Nanometers measure things at the atomic and molecular scale: wavelengths of visible light (400-700 nm), semiconductor features (3 nm transistors), DNA width (about 2 nm), and thin-film coatings.
Visible light spans about 400 nm to 700 nm, which is 4e-7 m to 7e-7 m.
No. Lowercase nm is the nanometer, a unit of length. Capitalized Nm (newton-meter) is a unit of torque and belongs to a different converter entirely.
A length in nanometers is zero or positive by convention. Negative values only appear for displacements or positions on a coordinate axis, not for sizes.
Exact. The SI prefix nano is defined as exactly 10^-9, so the conversion 1 nm = 10^-9 m has no approximation or rounding.
A human hair is about 80,000 nm wide, so it is about 26,667 times wider than a 3 nm transistor feature (80,000 / 3 = 26,666.67).
