Latent Heat Calculator

Enter the mass of an object and the specific latent heat of that object to calculate the latent heat in Joules.

Latent Heat Formula

The following equation can be used to calculate the latent heat of any object or material.

Q = m * L

  • Where Q is the latent heat (Joules)
  • m is the mass of the object (kg)
  • L is the specific latent heat.

Just as with specific heat, latent heat can be calculator through the mass and a constant that measure the objects ability to absorb heat. In the cases of latent heat, this is only the objects ability to absorb heat during phase transitions.

In other words, when i substance such as water is boiled, the temperature of the water does not change when it’s undergoing the phase change to a gas. Only when the water is in a gaseous state does the temperature start to increase. The energy that is dumped into the water during this time is considered to be the latent heat.
