Pascals to Newtons per Square Millimetre (Pa to N/mm2)
1 pascal (Pa) = 0.000001 newtons per square millimetre (N/mm²). 1 N/mm² = 1000000 Pa. Example: 15 Pa = 15 × 0.000001 = 0.000015 N/mm².

How to Convert Pascal to Newton per Square Millimetre
- 1 Pa = 0.000001 N/mm²
- 1 N/mm² = 1000000 Pa
- Example: convert 15 Pa to N/mm²: 15 Pa = 15 × 0.000001 N/mm² = 0.000015 N/mm²
Formula
N/mm² = Pa ÷ 1000000
Derivation from SI units:
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
- 1 N/mm² = 1 N ÷ 10⁻⁶ m² = 10⁶ Pa = 1 MPa
Both units are defined exactly, so the factor is exact. Pascal definition: pascal; Newton per Square Millimetre definition: newton per square millimetre.
Worked examples
- A reading of 125 Pa converts to 0.000125 N/mm².
125 Pa × 0.000001 = 0.000125 N/mm² - A value of 1000 Pa is 0.001 N/mm².
1000 Pa × 0.000001 = 0.001 N/mm²

Where it's used
Pascals are used for cleanroom and isolator pressure differentials (typically 10–50 Pa), while newtons per square millimetre appear in steel yield and tensile strength (S355: 355 N/mm²). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many newtons per square millimetre are in 1 pascal?
1 Pa = 0.000001 N/mm².
How do I convert pascals to newtons per square millimetre?
Multiply the value in Pa by 0.000001, or divide it by 1000000. For example, 15 Pa × 0.000001 = 0.000015 N/mm².
Is the Pa to N/mm² conversion exact?
Yes. Both units are defined exactly, and 1 Pa is exactly 0.000001 N/mm².
