About Inductance

Inductance is the property of an electrical conductor that opposes a change in current. It has units of henries (H).

• Henry (H) - SI unit of inductance.
• Millihenry (mH) - 1 mH = 10⁻³ H.
• Microhenry (μH) - 1 μH = 10⁻⁶ H.
• Nanohenry (nH) - 1 nH = 10⁻⁹ H.
• Picohenry (pH) - 1 pH = 10⁻¹² H.
• Kilohenry (kH) - 1 kH = 1000 H.
• Megahenry (MH) - 1 MH = 1,000,000 H.
• Abhenry (abH) - CGS unit, 1 abH = 10⁻⁹ H.
• Stathenry (stH) - CGS electrostatic unit, very large, ≈8.9876×10¹¹ H.

Inductance Units – A Guide to Inductive Reactance Measurement

Units of inductance play a key role in measurement of the electric circuit property that resists change in current flow. Inductance is typically seen in the devices such as inductors, transformers, and electromagnets and underlies the operation of AC circuits, radio frequency devices, and many other electric technologies. Knowledge of various units of inductance helps engineers, physicists, and technicians to design and analyze electric systems.

Basic Inductance Units

• Henry (H) – The SI unit for inductance is the henry (H). It is the inductance of a coil with the current through the coil increasing at a rate of one ampere per second and inducing one volt of electromotive force. It's the principal unit used for inductance in most electrical and electronics applications.
• Millihenry (mH) – A millihenry is one-thousandth of a henry (0.001 H). Millihenry is often employed to indicate the inductance of power supply and low-frequency inductors.
• Microhenry (μH) – A microhenry is one-millionth of a henry (10⁻⁶ H). The unit is often employed in high-frequency technology, for instance, radio and microwave systems, where lesser inductances are required.
• Nanohenry (nH) – One nanohenry (nH) equals one-billionth of a henry (10⁻⁹ H). It proves useful in sophisticated technologies operating at very high frequencies, such as radio-frequency circuits and high-speed signal processing.
• Picohenry (pH) – One picohenry equals one-trillionth of a henry (10⁻¹² H). Picohenry is used in highly sensitive and very precise applications, particularly in the application of high-frequency circuits and high-end telecommunication.
• Kilohenry (kH) – Thousand henries (1,000 H) is denoted by kilohenry (kH). Though not common in everyday applications, kilohenry is applied in power distribution and industrial systems, where a lot of inductance is required.
• Megahenry (MH) – Million henries (1,000,000 H) is equivalent to a megahenry (MH). The unit is widely applied in large electrical engineering applications, including the transmission of power and large inductive systems.
• Abhenry (abH) – The abhenry (abH) is a Gaussian system unit and is defined as 10⁻⁹ henries. It is largely used in antiquated measurement systems or highly technical and scientific applications.
• Stathenry (stH) – Stathenry (stH) is a unit of a practical system of units. It's equivalent to 10⁻¹⁰ henries and is largely used in specialized fields like magnetism and electromagnetism.
