While it might sound like a specialized term from a sci-fi novel, the abohm is a very real—though now dated—unit that once played a key role in how we measured the world. What Exactly is an Abohm? The abohm (
With the rise of the , specialized units like the abohm became obsolete. Modern standards, such as those from the IEEE and Merriam-Webster , typically label it as "dated" or recommend using the standard ohm instead. How to Convert It While it might sound like a specialized term
) is a unit of electrical resistance used in the system of units, specifically the electromagnetic version. In terms of scale, an abohm is incredibly small: 1 abohm = 10-910 to the negative 9 power ohms (or one billionth of an ohm). Modern standards, such as those from the IEEE
If you ever find yourself looking at old lab notes or vintage scientific papers, you might need to convert these units. You can use tools like the Inch Calculator for quick math, but the basic formula is simple: ABOHM Definition & Meaning - Merriam-Webster If you ever find yourself looking at old
Technically, a conductor has a resistance of one abohm if a current of one flowing through it produces a potential difference of one abvolt across its ends. A Quick History Lesson
The term "abohm" was introduced around by Arthur Edwin Kennelly. The "ab-" prefix stands for absolute , a nod to the "absolute electromagnetic system" used at the time.
