Linear Thermal Expansion Calculator
Calculate length change from initial length, thermal expansion coefficient and temperature change.
Linear Thermal Expansion Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- A 1 m object with a coefficient of 12×10⁻⁶/K expands by 1.2 mm when heated by 100 K.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Use ΔL=αLΔT. Enter the linear coefficient in 10⁻⁶/K.
scope of use
Assumes a constant coefficient, small strain and unconstrained expansion. Thermal stresses and structural safety are not calculated.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Assumes a constant coefficient, small strain and unconstrained expansion. Thermal stresses and structural safety are not calculated. Please compare the input unit, rounding method, applicable rules and data version first.
