What does attopascal measure?

Attopascal measures extremely low pressure or force per unit area, suitable for very small pressure scales such as those encountered in astrophysics or ultra-high vacuum conditions.

How is newton per square millimeter used?

Newton per square millimeter is a pressure or mechanical stress unit commonly used to specify material strengths and hydraulic pressures in engineering disciplines.

Why are the converted values so small?

Because 1 attopascal equals 10^-18 pascal, and conversion to newton per square millimeter involves scaling by 10^-24, resulting in extremely small numeric values.
