From unit
Nanometer (nm) — SI unit equal to one billionth of a meter
Used for wavelengths of light, molecular structures, and semiconductor features where dimensions are far below the micrometer scale
- Symbol: nm
- System: SI derived unit
- Exact relations: 1 nm = 10⁻⁹ m = 0.001 µm = 10 Å
- Imperial/US equivalents: 1 nm ≈ 0.0000000393700787 in
- Typical examples: visible light ~400–700 nm; DNA double helix diameter ~2 nm; advanced transistor features on the order of single-digit nanometers
To unit
Micrometer (µm) — SI unit equal to one millionth of a meter
Used in precision engineering, microscopy, and semiconductor manufacturing for dimensions far below a millimeter
- Symbol: µm (also called micron)
- System: SI derived unit
- Exact relations: 1 µm = 10⁻⁶ m = 0.001 mm = 10⁻⁴ cm
- Imperial/US equivalents: 1 µm ≈ 0.0000393700787 in
- Typical examples: human hair ~70 µm; bacteria ~1–10 µm; semiconductor features in the sub-µm to tens of µm range
