Convert Kilopascal to Pascal
1 kilopascal = 1,000 pascal (Pa). For example, 10 kilopascal = 10,000 pascal and 100 kilopascal = 100,000 pascal. Type any value below to convert kilopascal to pascal both ways — it runs entirely in your browser.
Quick answer: Kilopascal to Pascal
1 Kilopascal = 1,000 Pascal (kPa → Pa). To convert kilopascal to pascal, multiply by 1,000. To convert pascal to kilopascal, multiply by 0.001. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common kilopascal-to-pascal questions.
How to convert Kilopascal to Pascal
To convert kilopascal to pascal, multiply the number of kilopascal by the conversion factor 1,000, because 1 kPa = 1,000 Pa. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 Pa = 0.001 kPa, so you divide by 1,000 (or multiply by 0.001) to turn pascal back into kilopascal.
Pa = kPa × 1,000 ·
kPa = Pa × 0.001
- Write down the value you want to convert, in kilopascal.
- Multiply it by 1,000.
- The result is the same area/length/quantity expressed in pascal.

Kilopascal vs Pascal: which is bigger?
A kilopascal is the larger unit: one kilopascal equals 1,000 pascals. Put another way, you need 1,000 pascals to make a single kilopascal.
What is a Kilopascal? History, origin and usage
The kilopascal came into general use as countries converted their engineering standards to SI through the 1970s and 1980s. Canada, Australia and much of Europe moved tyre-pressure labels and gas-cylinder markings to kPa in that period, which is why a car built for one market often carries a door sticker in kPa and one built for another carries the same number in psi or bar.
Kilopascals are the workaday metric pressure unit: tyre pressures, medical gas supplies, water systems, ventilation and most mechanical engineering specifications. A car tyre is typically inflated to somewhere around 200 to 250 kPa.
One kilopascal is 1,000 pascals, and 100 kilopascals is very nearly one atmosphere — which is a useful mental shortcut, though the exact figure is 101.325 kPa, not 100.
What is a Pascal? History, origin and usage
The pascal is named after Blaise Pascal, who in 1648 had his brother-in-law carry a mercury barometer up the Puy de Dôme in central France and watch the mercury column fall as he climbed. That experiment showed air has weight and that the pressure it exerts drops with height. The unit itself is much younger: the name was adopted by the General Conference on Weights and Measures in 1971, replacing the older habit of writing pressures as "newtons per square metre".
The pascal is the SI unit of pressure and the base every other unit on this page is defined against. On its own it is awkwardly small for daily life — a sheet of paper resting on a table presses down with only a few pascals — so real-world figures are almost always given with a prefix: hectopascals for weather, kilopascals for tyres and gas, megapascals for concrete and hydraulics.
One pascal is one newton spread over one square metre, which is about the pressure of a five-rupee coin lying flat on a table. Because pressure is force divided by area, the same push concentrated into a smaller area gives a much higher pressure — which is why a drawing pin goes into a wall and your thumb does not.

Tips for converting Kilopascal to Pascal
- To go from kilopascal to pascal, multiply by 1,000; to go back, divide by 1,000 (or multiply by 0.001).
- For a quick mental estimate, remember that 1 kilopascal ≈ 1,000 pascal, so 10 kilopascal ≈ 10,000 pascal.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Kilopascal to Pascal converter
Type a number into the Kilopascal field and the equivalent in Pascal appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Pascal field to convert the other way (pascal to kilopascal). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 kPa = 1,000 Pa), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for kilopascal-to-pascal conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
Pressure factors here come from fixed definitions, anchored to the pascal: a bar is exactly 100,000 Pa, one atmosphere is exactly 101,325 Pa, a torr is exactly a 760th of an atmosphere, and psi is built from the exact pound and the exact inch. Two of them — psi and the torr — work out to decimals that repeat forever, so where a number is shown rounded it is marked, not quietly trimmed.
Frequently asked questions
- How many pascal are in 1 kilopascal?
- 1 kilopascal = 1,000 pascal (Pa). To convert any number of kilopascal to pascal, multiply by 1,000.
- How do I convert kilopascal to pascal?
- Multiply the number of kilopascal by 1,000. For example, 10 kilopascal = 10 × 1,000 = 10,000 pascal, and 25 kilopascal = 25,000 pascal.
- How many kilopascal are in 1 pascal?
- 1 pascal = 0.001 kilopascal. So to convert pascal back to kilopascal, multiply by 0.001.
- What is the formula to convert kilopascal to pascal?
- pascal = kilopascal × 1,000. The reverse formula is kilopascal = pascal × 0.001.
- How much is 100 kilopascal in pascal?
- 100 kilopascal = 100,000 pascal. (And 1000 kilopascal = 1,000,000 pascal.)
- Which is bigger, a kilopascal or a pascal?
- A kilopascal is larger: 1 kilopascal = 1,000 pascal.
- Is this kilopascal to pascal converter accurate?
- Yes — every value is computed from the exact 1,000 Pa per kPa factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert pascal to kilopascal too?
- Yes. The converter works both ways — enter a value in either field. 1 pascal = 0.001 kilopascal.
