The KSI is used to express the ultimate tensile strength (UTS) of any material. Steel with a UTS of 60,000 pounds per square inch could also be expressed as 60 KSI, with the "K" representing kilo or thousand. Sometimes, the UTS can be found expressed in Mpa or megapascals. To convert Mpa to KSI, the Mpa must be multiplied by 0.1450377.
