<p>Please note that this calculator calculates the heat (Q), mass (m), or latent heat (L) of a known substance. It uses the equation Q = mL, where Q is the heat energy, m is the mass, and L is the specific latent heat capacity. All inputs are
converted into SI units (J and kg) for calculation. If you want to calculate mixtures with solids, liquids or gases you will need to go to the <a href="[YOUR_LINK_HERE]" target="_blank" rel="noopener">mixture calculator</a> page. For more
information about specific latent heat capacity and the equation used in this calculator, please visit our <a href="[YOUR_LINK_HERE]" target="_blank" rel="noopener">specific latent heat</a> page.
