Ohm-Centimeters to Ohm-Meters Converter (Ω·cm to Ω·m)
Convert Ohm-centimeters to Ohm-meters (Ω·cm to Ω·m) with ConverterHub’s precision materials calculator. Translate semiconductor wafer resistivity, soil resistivity survey data, and water purity measurements directly into base SI Ohm-meters.
Formula & Calculation: Ohm-Centimeters to Ohm-Meters
Because 1 meter equals 100 centimeters, converting from Ohm-centimeters to standard SI Ohm-meters requires dividing by 100 (or multiplying by 0.01):
Ω·m = Ω·cm ÷ 100
Or expressed as a multiplier:
Ω·m = Ω·cm × 0.01
Example Calculation: A geological soil resistivity survey for electrical grounding grid design records a ground resistivity of 5,000 Ω·cm. Converting to Ohm-meters:
Ω·m = 5,000 Ω·cm ÷ 100 = 50 Ω·m

Electrical Substation Grounding Grid Design
In electrical power substation engineering according to IEEE Standard 80, four-pin Wenner soil resistivity surveys often gather data in Ohm-centimeters. However, substation grounding grid resistance formulas (such as Laurent-Niemann and Sverak equations) require soil resistivity (ρ) in Ohm-meters (Ω·m). Converting Ω·cm to Ω·m ensures accurate calculation of ground potential rise (GPR), touch voltage, and step voltage safety margins.

Frequently Asked Questions
How do I convert 250 Ω·cm to Ω·m?
Divide 250 by 100: 250 ÷ 100 = 2.5 Ω·m.
What is the relationship between resistivity and conductivity?
Resistivity and electrical conductivity are reciprocal properties: ρ = 1 / σ. If resistivity is in Ohm-meters (Ω·m), conductivity is in Siemens per meter (S/m). If resistivity is in Ohm-centimeters (Ω·cm), conductivity is in Siemens per centimeter (S/cm).
