air inductor calculator mm winding

Need to wind an 8.2 uH inductor. The insulated wires I've got, are 0.45mm,
0.5mm, 0.71 and 0.56mm. I've search the web for calculators, but no downloadable "single layer air core calculator' were to be found.
Should I rather wind an inductor with more layers. What are the advantages and disadvantages?

Any help would be apreciated

Regards
