Picometer (pm) — SI unit equal to one trillionth of a meter
Used to express atomic and subatomic dimensions such as bond lengths and ionic/atomic radii in chemistry and materials science
- Symbol: pm
- System: SI derived unit
- Exact relations: 1 pm = 10⁻¹² m = 0.001 nm = 10⁻⁶ µm = 0.01 Å = 1,000 fm
- Imperial/US equivalents: 1 pm ≈ 0.00000000003937007874 in
- Typical examples: covalent bond lengths ~100–200 pm; Bohr radius of hydrogen ~53 pm; atomic radii tens to a few hundred pm
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)
