136GPa
136 GPa refers to a pressure value of 136 gigapascals. A pascal is the SI unit of pressure, defined as one newton per square meter. A gigapascal is one billion pascals. Therefore, 136 GPa is equivalent to 136 billion pascals, or 136 x 10^9 N/m^2. This is an extremely high pressure, far exceeding atmospheric pressure at sea level, which is approximately 0.1 megapascals (MPa).
Pressures on the order of 136 GPa are typically found in scientific research, particularly in high-pressure
