Kilogram-Force/square Meter
Kilogram-force per square meter (kgf/m^2) is a unit of pressure representing the force of one kilogram-force applied over an area of one square meter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, before the adoption of SI units. It was commonly used in engineering and physics to measure pressure in contexts where gravitational force was considered.
Current Use
Today, kgf/m^2 is largely obsolete and replaced by the SI unit Pascal (Pa). However, it may still be encountered in legacy systems or specific regional applications related to pressure measurement.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
