How to Convert Decipascal to Ton-Force (Long)/square Inch
1 dPa = 6.47489900442821e-09 tonf (UK)/in^2
Example: convert 15 dPa to tonf (UK)/in^2:
15 dPa = 15 × 6.47489900442821e-09 tonf (UK)/in^2 = 9.71234850664231e-08 tonf (UK)/in^2

Decipascal
The decipascal (dPa) is a unit of pressure equal to one-tenth of a pascal, where 1 dPa = 0.1 Pa.
History/Origin
The decipascal was introduced as a metric unit to provide finer measurement options within the pressure unit system, though it is rarely used in practice due to the widespread adoption of the pascal.
Current Use
The decipascal is seldom used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific contexts or educational settings for illustrative purposes.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
