Find accurate atomic mass values for any chemical element instantly. Enter element names or symbols to get atomic weights for chemistry calculations, stoichiometry, and lab work.
Enter either the full element name (e.g. 'Hydrogen') or its symbol (e.g. 'H')
Enter an element name or symbol above to see its atomic mass and information.
The Elemental Mass Calculator provides the atomic mass and other information for chemical elements. The atomic mass is measured in atomic mass units (u), which is approximately the mass of a single proton or neutron.
To use this calculator, simply enter the name of an element (like 'Carbon') or its symbol (like 'C') in the input field above. The calculator will display the element's information, including its atomic mass.
