HHV to LHV Calculator – Accurate Results

This tool converts High Heating Value (HHV) to Low Heating Value (LHV) for various fuels, making energy analysis easier for you.




How to Use the Calculator

To use the Higher Heating Value (HHV) to Lower Heating Value (LHV) calculator, simply input the HHV of the fuel in MJ/kg and the water content percentage of the fuel. Click “Calculate” to get the LHV in MJ/kg.

Explanation of the Calculation

This calculator determines the Lower Heating Value (LHV) of a fuel based on its Higher Heating Value (HHV) and its water content. The formula used is:

LHV = HHV - (2.442 * (Water Content / 100))
The water content is given as a percentage, and the constant 2.442 is the latent heat of vaporization of water in MJ/kg.

Limitations

This calculator assumes that the latent heat of vaporization of water is a constant 2.442 MJ/kg, which is an approximation. Real-world conditions may slightly vary this value. Additionally, the calculator does not account for other factors that can influence HHV and LHV such as fuel impurities and measurement inaccuracies.
