Table shows common constants used in physics and chemistry.
Table shows composition (including mass ratio) of common cooling mixtures i.e. mixtures used to achieve low temperatures.
Table shows lattice crystal energy in kJ/mol for selected ion compounds.
Density units converter - converts units between kilograms per cubic meter, grams per liter, ounces per galon etc. Both metric and imperial (US and UK) units are included. Also, you will find more exotic units here, such as multiplicity of Earth density or femtograms per liter.
Table shows density of selected gases, solids and liquids.
Converts dipole moment from one unit to another e.g. from debyes to atomic units or vice versa.
Table shows values of electric dipole moment of various chemical substances given in any unit you prefer such as debyes, coulomb times meter, atomic units of dipole moment etc.
Table shows dissociation constants of selected chemical substances in temperature 298K (25°C).
Table shows overpotential values on selected electrodes.
Table shows electronic affinity (i.e. the amount of energy released when an electron is added to atom) for most of chemical elements.
Table shows electron configuration of chemical elements in groundstate.
Table shows basic properties of elementary particles.
Table shows flame colors specific to given chemical elements such as yellow-orange for sodium (Na), red-cherry for lithium (Li) etc.
Table shows electrochemical potential of selected elements i.e. so-called galvanic series.
Table shows ionization energy of chemical elements given in kJ/mol.
Table shows solubility equilibriums of selected substances, mainly sparingly soluble salts and hydroxides.
Table shows solubility of various substances under different temperature given in grams of dissoluted substance per 100g of water.
Table shows solutions color characteristic to given ions (cations or anions) such as Cu2+ (blue) or MNO4- (purple).
Table shows isotopic composition of chemical elements occuring permanently in nature. Isotopes obtained artificially are not presented here.
Convert volume to mass and vice versa. Using this calculator you can check what is the weight of a glass of water or what volume does kilogram of feathers occupy. Use the one of predefined substances (water, steal, wood etc.) or enter custom density in any unit (kg/m3, g/cm3, mg/l etc.)
Table shows how density of water depends on temperature. Data were measured under so-called normal pressure i.e. 1013,25 hPa.
