Often confused, PSI and KSI are really just a conversion of one another. In terms of advertising our wire PSI and KSI represent minimums relative to breaking strength.
PSI=Pound per square inch
KSI=Kilo-pound per square inch=1000 PSI
210 KSI=210,000 PSI
PSI used to calculate the breaking strength of wire
Area=(½ x diameter)² x Π
Where minimum breaking strength is =Area x PSI
Example: 12½ gauge, 210,000 PSI wire
Area= (½ x .099″)² x 3.14=0.0077″²
Min. breaking strength=0.0077″² x 210,000 PSI= 1617 pounds
*This particular wire can withstand a force of up to 1600 pounds, before breaking.
