How to use Linear Interpolation Calculator

For each query, interpolate between its two adjacent samples. Exact endpoints retain their supplied values.

  1. Enter increasing sample x, matching sample y, query x values.
  2. Check the model, units, and supported limits before calculating.
  3. Run the tool, inspect the result, then copy or download it.

Good to know

  • 2–1000 samples and 1–100 queries. X must increase strictly. Out-of-range queries are rejected; no hidden extrapolation.
  • Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
