Centimeter (cm) — one hundredth of a meter
Common in consumer products and human body measurements. Convenient for small dimensions in engineering, crafts, and design.
- Symbol: cm
- System: SI derived unit
- Exact relations: 1 cm = 0.01 m = 10 mm
- Imperial/US equivalents: 1 cm = 0.393700787 in (since 1 in = 2.54 cm exact)
- Typical examples: garment sizing, paper formats, device thickness
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
