There are many applications for quantities of energy per unit mass. The SI unit is J/kg.
Here are some examples:

The **heat of combustion** (Δ_{c}H^{0}) is the energy released as heat
when a compound undergoes complete combustion with oxygen. This may be related to the mass.
Values like the **Higher Heating Value (HHV)**, the **Lower Heating Value (LHV)**,
or the **Gross Heating Value (GHV)** have the same unit. They differ due to the treatment
of the water formed during the combustion process.

Other terms with the same units are the **specific energy**, the **specific enthalpy**,
the **thermal heat capacity**, the **latent heat**, the **energy efficiency** and many others.

**Usage:**
Type the value to convert into the field, behind which you find the unit.
Click on any empty space in the window or on the "calculate" button.
Read the result in the other fields.
Use the "reset" button to reset your calculation.
Move the mouse over a unit or click on it to read its full name.

**Example:**
Wood has a gross heating value of about 15 MJ/kg. How much is this in Btu/lb ?
Type "15" into the field behind which "MJ kg^{-1}" is written.
Click on any empty space in the window or on the "calculate" button.
Read the result in the other fields. (e.g. 6448.8 Btu_{IT}/lb).

**Remarks:**

- Please note the remarks about the
representation of numbers..

- There is no warranty for the calculation. Cactus2000 is not
responsible for damage of any kind caused by wrong results.

- Please send an email if you have suggestions or if you would like to see more
conversions to be included.
