'Сто' (sto) comes from the Proto-Slavic *sto, with further roots leading back to the Proto-Indo-European *ḱm̥tóm, which means 'hundred'. This numeral has remained relatively unchanged over time.
'Сто' is widely used in both spoken and written Russian, suitable for formal and informal situations. The term is consistent across Russian-speaking regions.
