Ohm (Ω)
Definition: The ohm (symbol: Ω) is the SI derived unit of electrical resistance. It is named after German physicist Georg Simon Ohm and is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied to these points produces a current of one ampere.
History/origin: The unit was formally defined in 1861 by the British Association for the Advancement of Science. It was part of Georg Ohm's discovery of Ohm's Law, which states that current is proportional to voltage and inversely proportional to resistance.
Current use: The ohm is the standard unit for measuring resistance in all types of electrical circuits, components (like resistors), and electronic devices.
Kiloohm (kΩ)
Definition: A kiloohm (symbol: kΩ) is a multiple of the ohm, equal to one thousand (1,000) ohms.
History/origin: The kiloohm became a standard unit with the birth of modern radio and telecommunications, where higher resistance values were needed to control small currents in vacuum tubes and transistors.
Current use: Kiloohms are the most widely encountered unit for general-purpose resistors used in everyday electronic circuits, sensors, and audio equipment.

How to Convert Ohm (Ω) to Kiloohm (kΩ)
1 ohm = 0.001 kohm
1 kohm = 1000 ohm
Example: convert 15 ohm to kohm:
15 ohm = 15 × 0.001 kohm = 0.015 kohm
Did You Know?
- Did you know? Electrical resistance is like friction for electricity. Every material has some resistance; materials with very low resistance are called conductors (like copper), while those with extremely high resistance are insulators (like rubber).
- Kiloohms (kΩ) are very common in electronics. Most resistors used in hobbyist projects and consumer electronics like your television or remote control are rated in kiloohms.
