API, OpenAPI and WebMCP documentation

Explanation

Multiply by 0.001 because 1 MPa = 1000000 Pa and 1 GPa = 1000000000 Pa.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Megapascal = 0.001 Gigapascals (using exact pascal-based stress definitions).
Consistency rule: calculator output and table values use the same constants and rounding policy.

Questions & answers

Frequently Asked Questions

Why is 1 megapascal only 0.001 gigapascal?

Because the giga- prefix is one thousand times larger than the mega- prefix, so 1 MPa is exactly 0.001 GPa.
