13 FOCUSED TOOLS
Heat & thermal change calculators
Estimate heating energy, phase-change energy and expansion.
Choose the right calculation
Heating within a phase uses specific heat; phase changes use latent heat. Material properties vary with temperature. Ideal conduction calculations omit several real-world heat-transfer paths.

Heat Energy Calculator
Estimate thermal energy for a temperature change without a phase change.
Thermal Expansion Calculator
Estimate length change using a constant linear expansion coefficient.
Heat Conduction Calculator
Find steady heat-transfer power through a uniform flat layer.
Latent Heat Calculator
Calculate energy for a phase change at constant temperature.
Thermal Resistance Flat Layer Calculator
Find thermal resistance of an ideal uniform planar layer.
Heat Pump COP Calculator
Compare delivered heating energy with electrical input for a measured interval.
Carnot Efficiency Calculator
Find the Carnot thermal-efficiency limit from absolute reservoir temperatures.
Ideal Gas Isothermal Work Calculator
Estimate reversible work during an isothermal ideal-gas volume change.
Ideal Gas Internal Energy Change Calculator
Calculate ideal-gas internal-energy change using an entered heat capacity.
First Law Heat Calculator
Apply the first law of thermodynamics with an explicit work-sign convention.
Thermal Energy Mixing Temperature Calculator
Estimate equilibrium temperature after mixing two quantities of the same substance.
Stefan Boltzmann Radiation Calculator
Estimate net radiative heat transfer with a stated emissivity.
Wien Peak Wavelength Calculator
