Convert Kilopascals to Pascals - Pressure Converter
This converter transforms pressure values given in kilopascals (kPa) into pascals (Pa). Both are SI units of pressure: the pascal is the base SI unit, and the kilopascal is a convenient multiple commonly used in engineering and atmospheric science.
The relationship between the units is exact and fixed, so numeric conversion is a simple scale factor. Use the guidance below for clear calculation steps, recommended significant-figure handling, and practical notes about measurement uncertainty and calibration when applying converted results in technical or regulatory contexts.

Methodology
The conversion is a direct scaling based on the SI definition: one kilopascal equals one thousand pascals. No empirical data or approximations are involved in the unit conversion itself.
When converting measured values, maintain and propagate the original measurement's uncertainty and instrument resolution. Converting units does not change absolute uncertainty, but the numeric uncertainty must be scaled by the same factor.
For engineering, lab reporting, or compliance use, follow traceability and calibration practices consistent with national and international standards such as NIST guidance and ISO/IEC 17025 accreditation for calibration laboratories. Safety standards and workplace limits from regulatory bodies should be consulted where pressure limits apply.
Worked examples
5 kPa → 5 × 1000 = 5000 Pa
0.2 kPa → 0.2 × 1000 = 200 Pa
101.325 kPa (approx. atmospheric pressure at sea level) → 101325 Pa
F.A.Q.
How many pascals are in 1 kilopascal?
One kilopascal equals exactly 1000 pascals.
Does converting units change measurement uncertainty?
No. Converting units scales the numeric value and any reported uncertainty by the same factor. The absolute uncertainty is multiplied by 1000 when converting kPa to Pa; relative uncertainty remains the same.
How should I round the converted result?
Match the number of significant figures to the precision of the original measurement or to the required reporting standard. Avoid introducing false precision by adding more digits than the measurement supports.
Which unit should I use for engineering calculations?
Use pascals when a base SI unit is required or when working with formulas that expect SI base units. Kilopascals are often used for readability in engineering documents and field work. Ensure consistency across calculations.
What calibration or standards considerations apply when reporting pressure?
Ensure instruments used for pressure measurement are calibrated and traceable to recognized standards. Laboratories commonly follow ISO/IEC 17025 for calibration procedures and NIST traceability recommendations. For workplace exposure or safety limits, consult relevant regulatory standards.

Semantic versioning
- MAJOR: Calculation outputs can change for the same inputs (formula, rounding policy, assumptions).
- MINOR: New features or fields that do not change existing outputs for the same inputs.
- PATCH: Bug fixes, copy edits, or accessibility changes that do not change intended outputs except for previously incorrect cases.
Review protocol
- Verify formulas and unit definitions against primary standards or datasets.
- Run golden-case regression suite and edge-case suite.
- Record reviewer sign-off with credentials and scope.
- Document assumptions, limitations, and jurisdiction applicability.
Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
