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.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

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.
