How to Convert Dekapascal to Ton-Force (Long)/square Inch
1 daPa = 6.47489900442821e-07 tonf (UK)/in^2
Example: convert 15 daPa to tonf (UK)/in^2:
15 daPa = 15 × 6.47489900442821e-07 tonf (UK)/in^2 = 9.71234850664231e-06 tonf (UK)/in^2

Dekapascal
The dekapascal (daPa) is a unit of pressure equal to ten pascals, where one pascal (Pa) is the SI derived unit of pressure representing one newton per square meter.
History/Origin
The dekapascal was introduced as a metric prefix-based unit to simplify the expression of larger pressures, particularly in fields like meteorology and engineering, aligning with the SI system's prefixes. Its usage is relatively uncommon compared to the pascal.
Current Use
The dekapascal is occasionally used in scientific and technical contexts to express pressure measurements more conveniently, especially in applications where pressures are in the range of thousands of pascals. It is part of pressure conversions within the 'Common Converters' category.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
