What is the Thermal Expansion Calculator?

The Thermal Expansion Calculator helps students, engineers, and physics enthusiasts determine how much a material expands or contracts when its temperature changes. By entering the initial length of the material, its coefficient of linear expansion, and the temperature change, the tool calculates the change in length, ensuring accurate results for experiments, design calculations, or practical applications. This prevents manual calculation errors and allows users to quickly understand the effect of temperature on materials.

How to Use:

1. Enter Initial Length (L₀, m): Input the original length of the material in meters.
2. Enter Coefficient of Linear Expansion (α, 1/K): Input the material’s linear expansion coefficient.
3. Enter Temperature Change (ΔT, K): Input the change in temperature in Kelvin.
4. Click “Calculate”: The tool computes the change in length using the formula ΔL = α·L₀·ΔT.
5. Review Result: The output displays the calculated change in length in meters and ensures the values entered are valid and positive for accurate computation.
