The formula is printed in the Radiotron Designer Handbook 4th edition, and depends on both the load presented to the power supply RL = voltage of power supply/current drawn by load, and the AC frequency. For a 50 Hz supply,L = RL/940
For a 60 Hz supply,
L = RL/1130.
These are approximate values to achieve continuous current flow according to the RDH. If I read the text correctly, this also suggests that below the critical inductance the current flow is not continuous during the whole cycle.
