Calculate the thermal expansion in millimeters (mm) of a FR4 PCB in X/Y direction. A typical temperature difference default is 65°C, the difference between 20°C room temperature and the max temperature rating of 85°C parts. The default 13ppm/°C thermal expansion coefficient is from this website.

You can enter values with SI suffixes like 12.2m (equivalent to 0.012) or 14k (14000) or 32u (0.000032).
The results are calculated while you type and shown directly below the calculator, so there is no need to press return or click on a Calculate button. Just make sure that all inputs are green by entering valid values.
