How it works
Use linear thermal expansion with the units stated beside the fields. This form solves for temperature difference magnitude; enter the known quantities in Length expansion magnitude, Linear expansion coefficient, Length.

Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the temperature difference magnitude result?
This model uses positive magnitudes. Use initial length and the small-expansion approximation. Coefficient is constant over the interval; only positive expansion is solved.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
