Ton-Force (Long)/square Foot
Ton-force (long) per square foot is a unit of pressure representing the force exerted by one long ton (2,240 pounds) distributed over one square foot.
History/Origin
This unit originated in the UK as a practical measure for engineering and industrial applications, combining the long ton (used primarily in the UK) with square foot to measure pressure in contexts such as structural and mechanical engineering.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units like pascals. It may still appear in historical data, specialized fields, or regional contexts within the UK.
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.
