Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
The volumetric heat capacity of a material is the heat capacity of a sample of the substance divided by the volume of the sample. It is the amount of energy that must be added, in the form of heat, to one unit of volume of the material in order to cause an increase of one unit in its temperature.
A mass-derived unit of volume is defined by reference to the density of some material. One common such material is water, used in multiple units. For the cubic ton, the situation is more complex—there are different cubic tons for different materials. The 1964 Reader's Digest Great Encyclopaedic Dictionary gave the following ton-derived volumes:

The fluid ounce derives its name originally from being the volume of one ounce avoirdupois of water, [21] but in the US it is defined as 1 ⁄ 128 of a US gallon. Consequently, a fluid ounce of water weighs about 1.041 ounces avoirdupois.
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Many drums nominally measure just under 880 millimetres (35 in) tall with a diameter just under 610 millimetres (24 in), and have a common nominal volume of 208 litres (55 US gal) whereas the barrel volume of crude oil is 42 US gallons (159 L). In the United States, 25-US-gallon (95-litre) drums are also in common use and have the same height.
