Kilopascals to Pascals Converter
Convert kilopascals to pascals — multiply by a thousand. Results update as you type; exact factors shown.
One kilopascal is 1,000 pascals — see the exact factor, not a rounded rule of thumb.
How the kilopascals to pascals converter works
Pressures convert through the pascal (1 N/m²). One bar is exactly 100 kPa; a standard atmosphere is exactly 101.325 kPa; 1 psi is 6.894757 kPa (a pound-force on a square inch); 1 mmHg is 133.322 Pa by the conventional definition.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about pressure conversion
How many pascals in a kPa?
1,000.
What is 220 kPa in Pa?
220,000 Pa — a typical car tyre.
When do I need pascals?
In physics and engineering equations, where SI base units keep the arithmetic consistent.
What is atmospheric pressure in Pa?
101,325 Pa at standard conditions.
What is a hectopascal?
100 Pa — the same as a millibar, used on weather charts.
