Please provide values below to convert nanopascal [nPa] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to nanopascal.
How to Convert Nanopascal to Ton-Force (Long)/square Inch
1 nPa = 6.47489900442821e-17 tonf (UK)/in^2
Example: convert 15 nPa to tonf (UK)/in^2:
15 nPa = 15 × 6.47489900442821e-17 tonf (UK)/in^2 = 9.71234850664231e-16 tonf (UK)/in^2

Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
