tsi - Tons per Square Inch (UK, Long) Pressure Unit
Tons or Tons Force per Square Inch (UK, Long) is a very large pressure unit used historically for measuring extremely high pressures. 1 Ton per Square Inch (UK, Long) equals 15,444,300 Pascals.
This Imperial version of Tons per Square Inch uses the United Kingdom long ton which is equal to 2,240 pounds (lbs).
Due to the high value of one tsi (uk, long) it is not used for common every day pressures and is mostly used when quoting pressures generated by geological forces or deep ocean depths. The tsi (uk, long) unit is also used as a measure of tensile strength of materials such as steel.
To convert one tfsi (uk, long) into other pressure units please see the table below.
For conversion to tfsi (uk, long) please click on the approriate unit below to obtain the value.
For multiple conversions to and from tsi (uk, long) use our online pressure calculator.

Formula
Pressure = Force / Area
Force = Mass x Acceleration
Acceleration = Distance / (Second x Second)
SI Units
Mass: Kilogram (kg)
Length: Metre (m)
Time: Second (s)
Force: Newton (N)
Pressure: Pascal (Pa)
Input Values
1 Ton (uk, long) = 2240 lbs
1 Pound = 0.45359237 kg
1 Inch = 0.0254 m
1 Square Inch = 0.0254 m x 0.0254 m = 0.00064516 m²
Acceleration = Standard Gravity = 9.80665 m/s²
Calculation
1 Ton Force (uk, long) = 2240 lbs x 0.45359237 kg x 9.80665 m/s² = 9964.016418 N
1 tsi (uk, long) Pressure = 9964.016418 N / 0.00064516 m² = 15444256.34 Pa
