Pascals to Kilopascals Converter
Convert pascals to kilopascals — divide by a thousand. Results update as you type; exact factors shown.
One pascal is 0.001 kilopascals — see the exact factor, not a rounded rule of thumb.
How the pascals to kilopascals 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 kilopascal?
Exactly 1,000.
What is 101,325 Pa?
One standard atmosphere, which is 101.325 kPa.
Why is the pascal so small?
One pascal is a newton per square metre — about the pressure of a sheet of paper lying on a table.
Which do gauges use?
kPa, because everyday pressures run to tens or hundreds of thousands of pascals.
What is 1 bar in Pa?
100,000 Pa.
