Ohm (Ω)
Definition: The ohm (symbol: Ω) is the SI derived unit of electrical resistance. It is defined as the resistance between two points of a conductor when a constant potential difference of one volt produces a current of one ampere.
History/origin: Named after the German physicist Georg Simon Ohm. It was formally defined in 1861 by the British Association for the Advancement of Science following Ohm's discovery of the mathematical law relating current, voltage, and resistance.
Current use: The ohm is the standard unit for measuring resistance in all types of electrical circuits, components (like resistors), and electronic devices globally.
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 development of radio and telecommunications, where higher resistance values were needed to control small currents.
Current use: Kiloohms are the most widely used unit for general-purpose resistors in smartphones, computers, and everyday consumer electronics.

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 extremely common in electronics. Most resistors used in household devices like your television or remote control are typically rated in kiloohms.
