Permeability: is webers per ampere-turn meter (Wb / At.m) equivalent to henrys per meter (H / m)?
The definition of inductance per turn is total flux per amp of current: -

$$L = \dfrac{\Phi}{I}$$

Dividing both sides by length, d gives equivalence for a one turn winding: -

$$\dfrac{L}{d} = \dfrac{\Phi}{I\cdot d}$$
