What is a Linear Interpolation Calculator?

A Linear Interpolation Calculator estimates unknown values between two known points on a straight line. It uses the linear interpolation formula to approximate a missing value.

Why Use a Linear Interpolation Calculator?

  1. Quick and Accurate Estimation – Saves time and reduces manual errors.
  2. Useful in Data Analysis – Helps estimate missing data points.
  3. Engineering & Science Applications – Used in physics, thermodynamics, and signal processing.
  4. Financial & Economic Analysis – Forecasting trends using existing data.

How Does a Linear Interpolation Calculator Work?

  1. Input Two Known Points – Given (x1,y1) and (x2,y2).
  2. Enter the Target x-Value – The x-value at which you need to find y.
  3. Apply the Linear Interpolation Formula:
  4. Compute and Display the Result – The calculator provides the estimated y-value.

When is a Linear Interpolation Calculator Used?

  • In mathematics & statistics – Estimating missing data points.
  • In engineering & physics – Approximating values in experiments.
  • In finance & economics – Predicting trends and market values.
  • In computer graphics & gaming – Interpolating animations and shading effects.
