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 on the left will give you a linear interpolation provided two data points are known. 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. |
