Is 'kilocycle' still used today?

No, it is an obsolete term. The International System of Units (SI) adopted 'hertz' (Hz) in 1960, making 'kilohertz' (kHz) the standard.

What is the direct modern equivalent of one kilocycle?

One kilocycle is exactly equal to one kilohertz (1 kHz).

Where might I encounter the word 'kilocycle'?

Primarily in historical documents, technical manuals, or radio equipment from before the 1970s.

Can 'cycle' on its own still mean 'hertz'?

In very specific technical contexts (like computing clock speeds), 'cycles per second' is informally understood, but 'hertz' is the formally correct unit.

Historical/Technical

My Flashcards

Definition

Meaning

A unit of frequency equal to one thousand cycles per second, chiefly used to measure radio waves.

An obsolescent technical term for a frequency of 1,000 hertz (1 kHz), used in older electronics and telecommunications contexts.

Linguistics

Semantic Notes

Now largely superseded by the SI unit 'kilohertz' (kHz). Its use indicates an older or historical technical document.

Dialectal Variation

British vs American Usage

Differences

No significant difference. The term was equally historical in both variants.

Connotations

Carries a mid-20th century, 'vintage technology' connotation.

Frequency

Extremely rare in contemporary use, found only in historical documents or by older specialists.

Business

Not used.

Academic

Found only in historical scientific papers on radio technology.

Everyday

Never used.

Technical

Used sparingly in historical or legacy system contexts; 'kilohertz' is the modern standard.

Examples

By Part of Speech

adjective

British English

The kilocycle measurement was standard for valve radios.

American English

The kilocycle frequency band is now obsolete.

Examples

By CEFR Level

The old radio manual listed the station frequency as 780 kilocycles.
Before kilohertz, engineers used the term kilocycle.

Early amplitude modulation broadcasts were confined to the 550 to 1600 kilocycle band.
The transmitter's output was calibrated precisely at 1000 kilocycles per second.

Learning

Memory Aids

Mnemonic

Think 'kilo-' (thousand) + 'cycle' (a full wave), making a thousand wave cycles per second.

Conceptual Metaphor

CYCLES ARE MEASURABLE WAVES

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct translation to modern Russian as 'килогерц' (kilohertz) is the standard term; 'килоцикл' is archaic.

Common Mistakes

Using 'kilocycle' in modern technical writing instead of 'kilohertz'.

Practice

Quiz

Fill in the gap

The vintage shortwave receiver was tuned to a frequency of 1200 , a unit long replaced by kilohertz.
