Orders of magnitude (inductance)

This page is a progressive and labeled list of the SI inductance orders of magnitude, with certain examples appended to some list objects.

List of orders of magnitude for inductance
SI prefix Value Item
10−42 N/A 1.62×10−42 H Planck inductance
10−12 Pico- (pH) 90×10−12 H Kinetic inductance (per square) of an MKID detector.[1]
10−9 Nano- (nH) 1×10−9 H Thin film chip inductor 1.6 × 0.8 mm with a typical power rating of 0.1 W. Range 1 100 nH.[2]
525×10−9 H One meter cat.5 cable pair.[3]
10−6 Micro- (µH) 1×10−6 H One meter of single wire, less for larger diameter.[4]
50×10−6 H Coil with 99 turns, 0.635 cm long with a diameter of 0.635 cm.
10−3 Milli- (mH) 1×10−3 H Coil 2.2 cm long with a diameter of 1.6 cm. with 800 mA capability. Used in kW amplifiers.[5]
100 (H) 1×100 H Inductor a few cm long and a few cm in diameter and having many turns of wire on a ferrite core.[6] Higher values than this is common only in audio and power supplies.[7]
8 .. 11×100 H Mains electricity transformer primary at 120 V.[8][9]
103 Kilo- (kH) 1.326×103 H 500 kV, 3000 MW power line transformer primary winding.[10]
