How to use the latent heat calculator
Find energy to melt or vaporise a substance. Enter mass, latent heat in the fields above; the energy, energy are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- m — Mass (kg)
- L — Latent heat (kJ/kg)
Worked example
With mass = 1 kg, latent heat = Melting ice, the calculator gives energy ≈ 334 kJ; energy ≈ 0.09277778 kWh.
Frequently asked questions
What is the formula for the latent heat calculation?
Energy (kJ) = m × L. Energy (kWh) = [Energy] / 3600. Here m is mass (kg), L is latent heat (kJ/kg).
What inputs do I need for the latent heat calculator?
You need mass in kg, latent heat in kJ/kg. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
