Inductance Converter
Henry (H)
Definition: The henry (symbol: H) is the SI derived unit of electrical inductance. It is defined as the inductance of a closed circuit in which an electromotive force of one volt is produced when the electric current in the circuit varies uniformly at a rate of one ampere per second.
History/origin: Named in honor of Joseph Henry (1797–1878), who discovered electromagnetic induction around the same time as Michael Faraday. It was officially adopted by the International Electrotechnical Commission in 1893.
Current use: The Henry is used to specify the inductance of large coils, power transformers, and heavy industrial inductors.
Microhenry (µH)
Definition: A microhenry is equal to one-millionth (10⁻⁶) of a henry.
History/origin: The development of radio and telecommunications in the early 20th century necessitated the measurement of much smaller inductance values, leading to the use of µH.
Current use: Widely used for high-frequency applications, RF filters, and small switching power supplies found in consumer electronics.

How to Convert Henry (H) to Microhenry (µH)
1 h = 1000000 uh
1 uh = 0.000001 h
Example: convert 15 h to uh:
15 h = 15 × 1000000 uh = 15000000 uh
Did You Know?
- Did you know? The unit "Henry" is named after Joseph Henry, an American scientist who discovered self-inductance independently of Michael Faraday around the same time!
- Microhenries (µH) are essential in radio technology. Small coils in your smartphone or Wi-Fi router use microhenries to tune into specific wireless frequencies.
