Examples
By Part of Speech
adjective
British English
- The kilohertz sampling rate
American English
- A kilohertz frequency signal
Examples
By CEFR Level
- This radio station is on 95 kilohertz.
- Human hearing can detect sounds up to about 20 kilohertz.
- The engineer adjusted the transmitter to the correct kilohertz frequency for the emergency broadcast.
- High-resolution audio often uses a sampling rate of 96 kilohertz to capture ultrasonic harmonics.
Learning
Memory Aids
Mnemonic
Think 'kilo' (thousand) + 'hertz' (cycles per second). Like a kilogram is a thousand grams, a kilohertz is a thousand hertz.
Conceptual Metaphor
Frequency as a wave count (a 'kilohertz' is a 'thousand waves per second').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct transliteration is 'килогерц' (kilogerts), which is the correct term.
- Avoid confusing 'hertz' (герц) with 'heart' (сердце).
Common Mistakes
- Spelling as 'kiloherts' or 'killobertz'.
- Incorrectly using it as a unit for speed or distance.
- Pronouncing the 'hz' as separate letters instead of 'hertz'.
