Convert gigapascal to kilonewton/square meter
Please provide values below to convert gigapascal [GPa] to kilonewton/square meter [kN/m^2], or Convert kilonewton/square meter to gigapascal.
How to Convert Gigapascal to Kilonewton/square Meter
1 GPa = 1000000 kN/m^2
Example: convert 15 GPa to kN/m^2:
15 GPa = 15 × 1000000 kN/m^2 = 15000000 kN/m^2

Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
Kilonewton/square Meter
A kilonewton per square meter (kN/m^2) is a unit of pressure equivalent to one kilonewton of force applied over an area of one square meter.
History/Origin
The kilonewton per square meter is derived from the SI units of force (newton) and area (square meter). It has been used in engineering and scientific contexts to measure pressure, especially in fields like civil and mechanical engineering, since the adoption of the SI system.
Current Use
Today, kN/m^2 is commonly used in engineering to specify stress, pressure, and load measurements, often interchangeably with the Pascal (Pa), where 1 kN/m^2 equals 1,000 Pa.
