Picofarads per meter to relative permittivity (dielectric constant)
Type a value in pF/m to get it in εr instantly.
0.4969εr
Nothing on our list is smaller: a vacuum is 2× higher.
Convert the other way: εr to pF/m
What it means
How strongly does it polarize?
Values are typical at low frequency and room temperature. Water’s permittivity falls sharply at microwave frequencies, which is how microwave ovens heat it.
The math
How to convert pF/m to εr
To convert picofarads per meter to relative permittivity (dielectric constant), multiply by 0.112941.
Example: 4.4 pF/m × 0.112941 = 0.49694 εr.
In the other direction, 1 εr = 8.85419 pF/m.
