How to convert ohm square millimeters per meter to ohm centimeters
Resistivity multiplied by length and divided by area gives resistance for a uniform conductor. Temperature and material state can change the measured resistivity.
Use x for the value in Ω·mm²/m, b for the intermediate value in Ω·m, and y for the result in Ω·cm.
Ω·cm = Ω·mm²/m × 0.000001 ÷ 0.01
Worked examples
10 Ω·mm²/m ≈ 0.001 Ω·cm
Step 1: (10 × 0.000001) ≈ 0.00001 Ω·m.
Step 2: 0.00001 ÷ 0.01 ≈ 0.001 Ω·cm.20 Ω·mm²/m ≈ 0.002 Ω·cm
Step 1: (20 × 0.000001) ≈ 0.00002 Ω·m.
Step 2: 0.00002 ÷ 0.01 ≈ 0.002 Ω·cm.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
