How to Use Linear Interpolation Calculation?
Step 1: First of all, input the value of X1 as first known x-coordinate in “Linear Interpolation Calculation” tool.
Step 2: Then, enter the corresponding Y1 value as first known y-coordinate in its respective input field.
Step 3: Now, input the value of X2 as the second known x-coordinate in field provided. Make sure X1 is not equal to X2 to avoid errors in calculation.
Step 4: Enter the corresponding Y2 value as the second known y-coordinate in respective input field.
Step 5: Next, input the desired Entry (X) value for which you want to calculate the interpolated Y value.
Step 6: Finally, click on Calculate button to get interpolated value of Y using the formula in a second.

Numerical Example of Linear Interpolation Calculation
Question:
Given the following data:
X1 = 99.5, Y1 = 1.269
X2 = 108, Y2 = 1.498
Entry (X) = 105.6
Calculate the interpolated value of Y.
Solution:
Step 1: Write formula for linear interpolation:
Y = Y1 + ( (Y2 – Y1) / (X2 – X1) ) * (X – X1)
Step 2: Substitute the given values:
Y = 1.269 + ( (1.498 – 1.269) / (108 – 99.5) ) * (105.6 – 99.5)
Step 3: Simplify the differences:
Y = 1.269 + (0.229 / 8.5) * 6.1
Step 4: Calculate the division and product:
Y = 1.269 + (0.02694 * 6.1)
Y = 1.269 + 0.16433
Step 5: Add the values:
Y = 1.433
Hence, The interpolated value of Y for X = 105.6 is 1.433.
[Note: Ensure all input values are accurate and that X1 is not equal to X2 to avoid division by zero errors.]
