Ohm Centimetre (Ω·cm)
The ohm centimetre is one hundredth of an ohm metre. Semiconductor wafers, soils and water resistivity are commonly quoted in Ω·cm.
Symbol: Ω·cm (ASCII: ohm*cm)
Quantity: electrical resistivity
SI relation: 1 Ω·cm = 0.01 Ω·m (exact)
Derivation: 1 Ω·cm = 0.01 Ω·m
Exact: yes, by definition
Typical uses
- Silicon wafer resistivity (for example 1–10 Ω·cm)
- Soil resistivity for earthing and corrosion surveys
- Water quality
