Ton-Force (Long)/square Inch
Ton-force per square inch (tonf/in²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square inch.
History/Origin
The ton-force (long) originated from the imperial system of units used in the UK, where it was defined as the force exerted by a long ton (2,240 pounds) under standard gravity. It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by pascals (Pa) or pounds per square inch (psi). It may still appear in legacy systems or specific industrial contexts in the UK.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
