Formula & Calculation: Microohm-Meters to Ohm-Centimeters
Because there are 10,000 microohm-meters in one Ohm-centimeter, convert from microohm-meters to Ohm-centimeters by dividing by 10,000 (or multiplying by 0.0001):
Ω·cm = μΩ·m ÷ 10,000
Or expressed as a multiplier:
Ω·cm = μΩ·m × 0.0001 = μΩ·m × 10⁻⁴
Example Calculation: A high-resistance Manganin shunt alloy has a bulk resistivity of 0.48 μΩ·m. Converting to Ohm-centimeters:
Ω·cm = 0.48 μΩ·m ÷ 10,000 = 0.000048 Ω·cm = 4.8 × 10⁻⁵ Ω·cm

Four-Point Probe Testing Standards
In semiconductor physics and thin-film metallurgy (such as SEMI and ASTM standards), sheet resistance (Rs) and bulk resistivity are measured using a collinear four-point probe. While metallurgical standards for thick bulk metals report resistivity in μΩ·m, thin films (such as sputtering targets and chemical vapor deposition layers) are traditionally characterized in Ω·cm. Converting between μΩ·m and Ω·cm ensures cohesive documentation across foundry and materials teams.

Frequently Asked Questions
How do I convert 15 μΩ·m to Ω·cm?
Divide 15 by 10,000: 15 ÷ 10,000 = 0.0015 Ω·cm.
Can sheet resistance be converted to resistivity?
Yes. Sheet resistance (Rs in ohms per square, Ω/□) is related to bulk resistivity (ρ) by the film thickness (t): ρ = Rs × t. If thickness is measured in centimeters, multiplying gives resistivity in Ω·cm, which can then be converted to μΩ·m by multiplying by 10,000.
