Core Formula (Linear Interpolation)

$y = y_1 + (x – x_1)\frac{y_2 – y_1}{x_2 – x_1}$y=y1​+(x−x1​)x2​−x1​y2​−y1​​-10-8-6-4-2246810-10-5510-8.00, -8.008.00, 8.00m = 1.00

This formula calculates the estimated value y based on surrounding known data points.

Practical Example

Let’s take a simple example:

• Known Points: (2, 4) and (6, 12)
• Target Value: x = 4

The calculator uses the interpolation formula to estimate the corresponding y value quickly and accurately.

Instead of solving it manually, you get an instant result, saving time and reducing effort.
