From unit
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
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
