Similar to GCV, NCV is typically measured in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (BTU/lb). NCV is particularly useful in applications where the heat generated is not fully utilized, such as in open fires or certain heating systems. By excluding the latent heat of vaporization, NCV provides a more ...
