Open calculatorGeothermal Gradient Calculator is an educational Earth Science tool for exploring a standard quantitative relationship.
Enter the requested values using the stated units. The calculator validates the numerical domain and applies gradient = (Tdepth − Tsurface) / depth.
Variables: Tsurface = Surface temperature (°C); Tdepth = Temperature at depth (°C); depth = Depth (km).
Example: 15°C at surface, 315°C at 10 km → 30°C/km.
It is intended for Earth Science study, classroom exercises and understanding the quantitative relationship represented by the model.
No. Real Earth systems can be more complex. The result should be interpreted within the assumptions, units and simplifications of the stated model.
