How to use
- Enter a value in the Pascals field.
- The Kilopascals figure appears immediately — no button to press.
- Typing in the Kilopascals field converts back to Pascals the same way.
- Use the reference table for the values that come up most often.
Pascals to Kilopascals formula
The factor from pascals to kilopascals is 0.001.
kPa = Pa × 0.001
Put another way, one pascal is exactly 1/1,000 of a kilopascal.
Why this factor: the pascal and the kilopascal are both defined against the pascal, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Kilopascals to Pascals converter, which is the same calculation reversed.
Worked example
Start with 100 Pa. Multiply by 0.001 to get 0.1 kPa.
100 Pa × 0.001 = 0.1 kPa
The converter above does this for any value you type, in either direction.
What is a pascal?
The pascal is the SI unit of pressure — one newton of force spread over one square meter.
Definition: Defined as 1 N/m². Named after Blaise Pascal.
Where it is used: Scientific and engineering pressure calculations, and weather pressure in hectopascals.
Worth knowing: A single pascal is a very small pressure, which is why weather reports use hectopascals and engineering uses kilopascals.
What is a kilopascal?
A kilopascal is 1,000 pascals, the practical metric pressure unit.
Definition: Exactly 1,000 pascals. Standard atmospheric pressure is 101.325 kPa.
Where it is used: Tyre pressures outside the US, weather reports in Canada, and structural engineering loads.
Pascals vs Kilopascals
The pascal is an SI unit while the kilopascal is a metric unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
Frequently asked questions
How many kilopascals are in a pascal?
One pascal equals 0.001 kilopascals.
What is the formula to convert pascals to kilopascals?
Multiply the number of pascals by 0.001. To reverse it, divide by 0.001 instead.
How do I convert kilopascals back to pascals?
Divide by 0.001, which is the same as multiplying by 1000.
How many kilopascals are in 10 pascals?
10 Pa works out to 0.01 kPa.
Is there anything to watch out for with pascals?
A single pascal is a very small pressure, which is why weather reports use hectopascals and engineering uses kilopascals.
How is the pascal defined?
Defined as 1 N/m². Named after Blaise Pascal.
