To convert between chemical names, formulas and Hill formulas, enter a chemical name or formula and click 'Convert'. In chemical formula you may use:
Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
Functional groups: D, T, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
This tool converts between different chemical notation formats including chemical names, molecular formulas, and Hill formulas.
What are chemical formulas?
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound. For example, water has the chemical formula H₂O, indicating that each molecule contains two hydrogen atoms and one oxygen atom.
What is a Hill formula?
A Hill formula is a specific way of writing molecular formulas where carbon comes first (if present), followed by hydrogen, then all other elements in alphabetical order. For example, glucose C₆H₁₂O₆ has the Hill formula C6H12O6, while sodium chloride NaCl remains NaCl. Hill notation is commonly used in chemical databases and literature for consistent compound identification.
Chemical naming conventions
Chemical compounds can be named using systematic IUPAC nomenclature or common names. For example, H₂O can be called 'water' (common name) or 'dihydrogen monoxide' (systematic name). This tool recognizes both systematic and common chemical names for conversion to formulas.
