Convert Terapascal to Gigapascal (TPa to Gigapascal)

Terapascal (TPa) and Gigapascal (Gigapascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert terapascal to gigapascal. This free online calculator tool makes it simple and easy to perform the conversion from TPa unit to the Gigapascal unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The terapascal (symbol: TPa) is an SI-derived unit of pressure equal to one trillion (10¹²) pascals. It is used primarily in materials science, high-pressure physics, geophysics, and planetary science to describe extremely high pressures. The terapascal uses the SI prefix tera, representing a factor of one trillion.

One terapascal is equal to 1,000 gigapascals, 1,000,000 megapascals, 10,000,000 bars, 1,000,000,000 kilopascals, and 1×10¹² pascals. Although rarely encountered outside scientific research, the terapascal is part of the complete SI pressure scale.

The gigapascal (symbol: GPa) is an SI-derived unit of pressure equal to one billion (10⁹) pascals. It is widely used in material science, structural engineering, mechanical engineering, and geology to express very high pressures and the elastic modulus of materials. The gigapascal uses the SI prefix giga, representing a factor of one billion.

One gigapascal is equal to 1,000,000,000 pascals, 1,000 megapascals, 1,000,000 kilopascals, 10,000 bars, and 145,037.738 pounds per square inch. The gigapascal is the standard unit for reporting the strength and stiffness of engineering materials.
