2 pascals (pa) is equal to 0.002 kilonewtons (kn).
This conversion is based on the relationship between pascals and newtons per square meter, and how newtons relate to kilonewtons. Since 1 pa equals 1 newton per square meter and 1 kn equals 1000 newtons, converting 2 pa to kn involves dividing by 1000.

Conversion Formula
The formula to convert pascals (pa) to kilonewtons (kn) is based on their definitions. A pascal is a unit of pressure equal to one newton per square meter (N/m²). A kilonewton is 1000 newtons. Since pascals measure pressure and kilonewtons measure force, converting requires consideration of the area involved.
However, if you consider the force over an area of 1 square meter, then:
Force (N) = Pressure (Pa) × Area (m²)
Given 1 m² area, force in newtons equals pressure in pascals. To convert newtons to kilonewtons, divide by 1000:
kn = (pa × 1) / 1000 = pa / 1000
Step-by-step for 2 pa:
- Multiply pressure by area: 2 pa × 1 m² = 2 N
- Convert newtons to kilonewtons: 2 N ÷ 1000 = 0.002 kn
Conversion Example
- Convert 15 pa to kn:
- Multiply 15 pa by 1 m² to get 15 N
- Divide by 1000 to convert to kn: 15 ÷ 1000 = 0.015 kn
- Convert 50 pa to kn:
- 50 pa × 1 m² = 50 N
- 50 N ÷ 1000 = 0.05 kn
- Convert 100 pa to kn:
- 100 pa × 1 m² = 100 N
- 100 N ÷ 1000 = 0.1 kn
- Convert 0.5 pa to kn:
- 0.5 pa × 1 m² = 0.5 N
- 0.5 N ÷ 1000 = 0.0005 kn

Conversion Definitions
Pa (Pascal): A pascal is the SI unit of pressure equal to one newton force applied over an area of one square meter. It measures how much force is exerted on a surface per unit area, useful in physics and engineering for quantifying pressure and stress.
Kn (Kilonewton): A kilonewton is a unit of force equal to 1000 newtons. It expresses larger forces encountered in structural engineering, mechanics, and physics, simplifying calculations by scaling up from newtons to thousands of newtons for easier interpretation.
Conversion FAQs
Can I convert pascals directly to kilonewtons without area?
No, because pascals measure pressure (force per area) and kilonewtons measure force. To convert pa to kn accurately, you must know the area over which the pressure is applied, otherwise the conversion assumes a unit area of 1 square meter.
Why is 2 pa equal to 0.002 kn in this example?
Here, 2 pa is pressure applied over 1 square meter area, so force = pressure × area = 2 N. Since 1 kn = 1000 N, 2 N equals 0.002 kn. It works because the area is assumed as 1 m² in the conversion.
What happens if the area is different from 1 square meter?
If the area changes, the force changes proportionally. For example, 2 pa over 2 m² is 4 N, which is 0.004 kn. So, area size affects conversion outcome, and must be considered.
Are pascals and kilonewtons measuring the same physical quantity?
No, pascals measure pressure (force per unit area), while kilonewtons measure force itself. They relate through area, but cannot be interchanged without it.
Is this conversion useful in everyday situations?
Conversions like pa to kn help engineers calculate forces from pressure readings, such as in hydraulics or structural loads, making it practical for design and safety considerations.
