Question 1

How do I convert GPa to bar?

Accepted Answer

Multiply by 10,000. 1 GPa = 10,000 bar. Diamond anvils can reach 500 GPa = 5 million bar.

Question 2

What is the pressure at Earth's core?

Accepted Answer

About 360 GPa (3.6 million atmospheres). Temperature is ~5,400°C. Iron is solid due to extreme pressure.

Question 3
