The heat of fusion of ice is 143.35 BTU per Lb.
This is the heat required to change the state of ice to water.

This is the amount of heat required to melt unit mass of ice while the temperature stays constant. For ice made from pure water, it is 336 J of heat to melt one kilogram at 0 C.

Conversely, you have to suck out 336 kg of heat from pure water at zero degrees to make it freeze.

Latent heat of fusion for ice is 334,000 J/kg

while latent heat of vaporization of water is 2,260,000 J/kg
