How much pressure is 1 Pa?

0.000 psi (0.001 kPa) is comparable to a laboratory vacuum, such as inside a glass bell jar.

Did you know? Outer space (LEO) is 0.001 kPa.

Low Earth orbit has virtually no pressure — about 10-7 Pa, which is considered a hard vacuum.

How to Convert Pascal to KPa

1 pascal = 0.001 kPa

KPa = Pascal × 0.001

Example: 1 Pa × 0.001 = 0.001 kPa

Reverse Conversion

To convert kPa back to pascals:

  • Remember, 1 kPa equals 1000 pascals.
  • To convert 0.001 kPa to Pa, multiply 0.001 x 1000, resulting in 1 Pa.

1 Pa is also equal to:

About these units

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).

KPa: SI-derived pressure unit equal to 1,000 pascals (10³ Pa).

Frequently Asked Questions

How much is 1 pascal in kPa?

1 pascal equals 0.001 kPa. This is calculated by multiplying 1 by the conversion factor 0.001.

What does 1 pascal look like in kPa?

1 pascal (0.001 kPa) is very low pressure — a gentle breeze creates about 1-10 Pa.

How do you calculate 1 pascal to kPa?

Multiply 1 by the conversion factor 0.001. The calculation is 1 × 0.001 = 0.001 kPa. This factor is defined by international measurement standards.
