What is the exact conversion rate from N/mm² to GPa?

One newton per square millimeter is exactly equal to 0.001 gigapascal.

Why convert from N/mm² to GPa?

Converting to gigapascal allows easier expression and comparison of very high pressure or stress values common in advanced materials science and engineering.

Can this tool account for temperature effects on pressure?

No, the conversion assumes pure numeric scaling and does not consider material-specific conditions such as temperature variations.
