Inductance Conversions

Inductance is the property in an electrical circuit where a change in the current flowing through that circuit induces an electromotive force (EMF) that opposes the change in current. In electrical circuits, any electric current i produces a magnetic field and hence generates a total magnetic flux Φ acting on the circuit. This magnetic flux, due to Lenz's law tends to act to oppose changes in the flux by generating a voltage (a back EMF) that counters or tends to reduce the rate of change in the current. The ratio of the magnetic flux to the current is called the self-inductance which is usually simply referred to as the inductance of the circuit.

The term "inductance" was coined by Oliver Heaviside in February 1886. It is customary to use the symbol L for inductance, possibly in honor of the physicist Heinrich Lenz. In honor of Joseph Henry, the unit of inductance has been given the name Henry (H). - Wikipedia

Standard unit = Henry (H)

  abhenry henry microhenry millihenry stathenry
1 abH = 1 10-9 0.001 10-6 1.113 * 10-21
1 H = 109 1 106 1000 1.113 * 10-12
1 µH = 1000 10-6 1 0.001 1.113 * 10-18
1 mH = 106 0.001 1000 1 1.113 * 10-15
1 statH = 8.987•1020 8.987•1011 8.987•1017 8.987•1014 1

Note: The prefix "ab" is used to indicate an electromagnetic unit in the centimeter-gram-second system.
          The  prefix "stat" is used to indicate an electrical unit in the electrostatic centimeter-gram-second system of units.
