Convert kilogram-force/sq. millimeter to ton-force (long)/square inch
Please provide values below to convert kilogram-force/sq. millimeter [kgf/mm^2] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to kilogram-force/sq. millimeter.
1 kgf/mm^2 = 0.634970683218 tonf (UK)/in^2. To convert kilogram-force/sq. millimeter to ton-force (long)/square inch, multiply the value by 0.634970683218; to go the other way, divide by it (1 tonf (UK)/in^2 = 1.57487585873 kgf/mm^2). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Kilogram-Force/sq. Millimeter
Kilogram-force per square millimeter (kgf/mm²) is a unit of pressure representing the force of one kilogram-force applied over an area of one square millimeter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, and was commonly used in engineering and material science to measure pressure before the adoption of SI units. Its usage has declined with the standardization of the pascal (Pa).
Current Use
Today, kgf/mm² is still used in some engineering fields, especially in material strength and pressure measurements, but it is largely replaced by SI units like the pascal (Pa) or megapascals (MPa).
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
