League - traditional distance unit
League is a historical unit of length with region-dependent values, commonly taken as about three miles on land; a nautical league is standardized as three nautical miles. Used historically in European surveying, travel descriptions, and maritime contexts
- Symbol: none standardized
- System: Historical (European/Imperial/Maritime)
- Common relations (land): 1 league ≈ 3 statute miles ≈ 4.828 km (English/US usage); varied by country (e.g., French/Spanish leagues ranged ~4–7 km)
- Nautical league (standardized): 1 nautical league = 3 nmi = 3 × 1,852 m = 5,556 m (exact) ≈ 5.556 km
- Typical examples: literary distances (“several leagues”); maritime references (e.g., coastal limits expressed in nautical leagues)
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
