Metric prefixes
Metric prefixes precedes a basic unit of measure to indicate a multiple or a fraction of the basic unit.
The commonly measures that uses prefixes are energy, length, mass, time and angles, volume, and some non-metric units (byte, decibel, pound, …).

Specific heat coefficient
The specific heat coefficient of a substance is the heat capacity divided by the mass. It is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in its temperature. The SI unit of specific heat is joule per kelvin and kilogram, J/(K kg).For example, at a temperature of 25 °C (the specific heat capacity can vary with the temperature), the heat required to raise the temperature of 1 kg of water by 1 K (equivalent to 1 °C) is 4.179,6 joules, meaning that the specific heat of water is 4.179,6 J·kg−1·K−1.

Conversion from one hardness scale to another is only an approximate process. Differents types of hardness tests do not all measure the same combination of material properties. Because of the wide range of variation among different materials, it is not possible to state confidence limits for the errors in using a conversion chart.
