kilovolt
Very LowTechnical / Scientific
Definition
Meaning
A unit of electromotive force equal to one thousand volts.
Primarily used in electrical engineering, physics, and power systems to measure high voltages, such as in power transmission lines, electrical equipment ratings, and scientific instrumentation.
Linguistics
Semantic Notes
This is a precise, quantitative term with no figurative uses. It is a compound of the metric prefix 'kilo-' (thousand) and the unit 'volt'. It is typically used in written specifications, technical documentation, and professional discourse.

Rare, except in contexts like purchasing specifications for industrial equipment.
Academic
Used in physics and engineering textbooks, research papers, and lab reports dealing with electricity.
Everyday
Virtually never used. A layperson would say 'thousands of volts'.
Technical
The primary register. Used in engineering designs, safety standards, equipment manuals, and utility company communications.
Examples
By Part of Speech
adjective
British English
- The 33-kilovolt cable needs replacing.
- They installed a new kilovolt-level transformer.
American English
- The 34.5-kilovolt line runs through the county.
- Check the kilovolt rating on the capacitor.
Examples
By CEFR Level
- The power lines carry electricity at many kilovolts.
- Do not touch equipment that uses kilovolts.
- The local substation steps down voltage from 11 kilovolts to 240 volts for homes.
- The experiment required a pulse of several kilovolts.
- The generator's output is stabilised at 6.6 kilovolts before being fed into the grid.
- Insulation breakdown occurred at approximately 150 kilovolts per metre.
Learning
Memory Aids
Mnemonic
Think of a 'kilo' of volts, just like a kilogram is a thousand grams. 'Kilo' always means thousand.
Conceptual Metaphor
VOLTAGE IS PRESSURE (A kilovolt is a high 'pressure' in an electrical circuit).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation 'киловольт' is correct and identical in meaning. No trap.
Common Mistakes
- Misspelling as 'killovolt' or 'kilowatt' (which is a unit of power, not voltage).
- Incorrect pluralization: 'kilovolts' is standard.
- Using in non-technical contexts where it sounds unnatural.

FAQ
Frequently Asked Questions
No, it is a specialised technical term used almost exclusively in engineering, physics, and the power industry.
A kilovolt (kV) is a unit of electrical potential (voltage), like pressure. A kilowatt (kW) is a unit of power, which is the rate of energy use or production. They measure different things.
The standard abbreviation is 'kV', where 'k' is for kilo and 'V' is for volt.
Extremely unlikely. In everyday contexts, people refer to 'volts' (e.g., a 9-volt battery) or describe high voltage qualitatively as 'thousands of volts' or 'high voltage'.
