What this calculator is for

Derive a linear reference-versus-indication calibration and correct a new indicated value. The workflow keeps every assumed property, state and coefficient visible so the result can be independently checked.

1Match the displayed relationship to the real system before entering data.
2Use one consistent unit basis and preserve absolute quantities where stated.
3Compare the intermediate results and retain the model boundary.

Visual explanation

The tailored schematic shows the direction of energy, signal, state change or reliability logic represented by the selected equation.

The governing relationship

reference=a·indication+b from two entered calibration pairs.

Keep the boundary visible

Two-point linear interpolation/extrapolation only; uncertainty, hysteresis, repeatability, drift and traceability are not created.

Quick guide

How to use this calculator

  1. Choose the analysis mode that matches the physical model before entering values.
  2. Enter properties, geometry, loads, states and coefficients from one consistent unit and sign convention.
  3. Use the intermediate outputs to audit the relationship, then retain the stated idealization before applying it.

Calculation method

Transparent engineering model

reference=a·indication+b from two entered calibration pairs.

The calculator evaluates only the declared relationship and preserves visitor-entered assumptions rather than selecting materials, factors, components or standards.

Worked example

Worked example

Indications 10 and 20 corresponding to references 11 and 21 produce slope 1 and intercept 1.

reference=a·indication+b from two entered calibration pairs.

Supported inputs

Precision and limits

Analysis, not approval

Two-point linear interpolation/extrapolation only; uncertainty, hysteresis, repeatability, drift and traceability are not created.

Standards and properties

Material properties, allowable values, load combinations, safety factors, correlations, manufacturer data, codes and jurisdictional requirements are not supplied automatically.

Units and precision

Use one consistent unit basis. Results retain working precision but cannot be more accurate than the entered measurements and properties.
