kilopascal
Very Low (C2/Technical)Technical/Scientific
Definition
Meaning
A unit of pressure equal to one thousand pascals, or one thousand newtons per square meter.
In technical contexts, a measure of stress or force per unit area; commonly used in meteorology for atmospheric pressure, and in engineering for material stress, fluid pressure, and tire inflation.
Linguistics
Semantic Notes
Always singular in form; abbreviation 'kPa' is frequently used in technical writing and labels. It is a decimal unit within the SI system.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or grammatical differences. Both regions use the SI unit identically. Spelling remains the same.
Connotations
Technical and precise in both contexts.
Frequency
Equally low frequency in everyday speech in both regions, confined to scientific, engineering, and meteorological contexts.

Usage
Context Usage
Business
Rare, except in technical manufacturing or engineering specifications.
Academic
Common in physics, engineering, meteorology, and materials science papers and textbooks.
Everyday
Virtually never used. Common replacements are 'pounds per square inch (PSI)' or simply 'pressure'.
Technical
The standard SI unit for reporting pressure in scientific journals, engineering blueprints, weather reports (in many countries), and safety standards.
Examples
By Part of Speech
adjective
British English
- The kilopascal reading was stable.
- A kilopascal gauge is fitted.
American English
- The kilopascal value is displayed.
- Check the kilopascal rating.
Examples
By CEFR Level
- The weather report said the air pressure is 101 kilopascals.
- Engineers specified that the chamber must withstand up to 250 kilopascals of internal pressure.
- The material's yield strength was tested under progressively increasing stress, measured precisely in kilopascals.
Learning
Memory Aids
Mnemonic
"KILO" means thousand (like kilogram), and a PASCAL is a small unit of pressure; so a KILOPASCAL is a thousand of those tiny pressure units.
Conceptual Metaphor
PRESSURE IS FORCE/WEIGHT (e.g., 'under the kilopascals of expectation').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'килопаскаль' in non-technical English conversation; use the English term or 'kPa'. In Russian, it is a direct cognate, but the concept is not used in daily life.
Common Mistakes
- Pronouncing 'pascal' like the name 'Pascal' /pæsˈkæl/; correct is /ˈpæskəl/.
- Using plural form 'kilopascals' as an adjective (e.g., 'a 100 kilopascals pressure' – should be 'a 100 kilopascal pressure').

FAQ
Frequently Asked Questions
No, it is a highly technical term used primarily in science, engineering, and meteorology.
A kilopascal (kPa) is equal to 1000 pascals (Pa). The pascal is a very small unit, so the kilopascal is more practical for many measurements.
In British English: /ˈkɪlə(ʊ)ˌpæskəl/. In American English: /ˈkɪloʊˌpæskəl/. The stress is on the first syllable.
In technical contexts, you must use the unit specified by the standard (SI uses kPa). In informal or regional contexts (e.g., US car manuals), PSI is common. They are different units: 1 kPa ≈ 0.145 PSI.
