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
Pole (also rod or perch) - traditional surveying length
Pole is a historical Imperial/US surveying unit equal to 16.5 feet. Used in land measurement, parcel descriptions, and traditional fencing
- Symbols: rd (rod), p (perch); no standard symbol for “pole”
- System: Imperial/US customary (historic surveying)
- Exact relations: 1 pole = 16.5 ft = 5.5 yd = 1/4 chain = 25 links = 1/320 mi
- Metric equivalents: 1 pole = 5.0292 m (exact)
- Typical examples: fence runs; plot dimensions in old deeds (e.g., “4 poles 3 links”)
