Convert Kilopascals to Pascals
Kilopascals to pascals is the conversion you reach for when a pressure is written in kPa but your formula, gauge, or datasheet wants the base SI unit. One kilopascal is exactly 1000 pascals, so the number always gets bigger — by a factor of a thousand — when you switch from kilopascals to pascals.

The formula
To convert kilopascals to pascals, multiply the number of kilopascals by 1000:
pascals = kilopascals × 1000
A worked example
Say you have a reading of 100 kPa and want it in pascals:
100 × 1000 = 100,000 Pa
So 100 kilopascals is exactly 100,000 pascals.
Why the number is exact
The pascal is the base SI unit of pressure, and the kilopascal is just the pascal with the "kilo" prefix, which means a thousand. So one kilopascal is exactly 1000 pascals by definition — an exact whole number, not an approximation. That's why the conversion never loses precision, no matter how many decimals you carry.
When you'll use it
Feeding a pressure value into an SI formula that expects pascals, reading engineering datasheets, or lining up a gauge marked in kPa with instruments or calculations that work in the base unit.
Frequently asked questions
How many pascals are in a kilopascal?
Exactly 1000 pascals. The 'kilo' prefix means a thousand, so a kilopascal is a thousand pascals — a fixed, exact number, not a rounded one.
How do I convert kilopascals to pascals in my head?
Multiply by 1000 — or just move the decimal point three places to the right. So 3.5 kPa becomes 3500 Pa.
Is the kilopascals to pascals conversion exact?
Yes. A kilopascal is defined as exactly 1000 pascals, so there's nothing rounded away — the conversion is exact at any number of decimal places.
