A system or practice based on hundredths or centesimal divisions; adherence to or promotion of metric thinking.
From 'centesimal' plus '-ism' (suffix indicating a system or ideology). This is an extremely rare, constructed term with minimal documented usage.
If 'centesm' were a real ideology, it would be the zealous belief in base-10 and base-100 for everything—and in France during the 1790s, revolutionary 'centesists' almost made it happen!
