Hecto (símbol h) és un prefix del Sistema Internacional que indica un factor de 102, o 100.
Adoptat el 1795, prové del grec ἑκατόν (hekatón), que significa cent.
Per exemple;
- 1 hectàrea = 1 ha = 100 àrees = 1 hm²
- 1 hectòmetre = 1 hm = 100 metres
- 1 hectogram = 1 hg = 100 grams
- 1 hectolitre = 1 hl = 100 litres
