Linear interpolation is often used to fill the gaps in a table. Suppose that
one has a table listing the pressures for saturated steam at various
temperatures, 360F, 370F, and 380F and that one needed to estimate the
pressure for 364F. Linear interpolation is an easy way to do this.

The interpolation calculator will give you a linear interpolation point (Yt) provided two data points are known (X0,Y0) & (X1,Y1). The accuracy is determined by how close the data points are to the input variable. The interpolation calculator was made so students, engineers, and scientists can quickly interpolate values on the fly.
