What is the thermal linear expansion for mild steel in inches?

The thermal linear expansion coefficient for mild steel is approximately 6.5 to 7.5 x 10^-6 inches per inch per degree Fahrenheit (in/in/°F). This means that for every degree Fahrenheit increase in temperature, a one-inch length of mild steel will expand by about 6.5 to 7.5 millionths of an inch. This property is important in engineering and construction to account for temperature-induced changes in dimensions.
