A unit of measurement for volume that is equal to 100 liters.
The recipe calls for two hectoliters of water.
Hectoliter → It is formed from "hecto-" (from Greek "hekaton", meaning hundred) and "liter" (from Latin "litera", meaning a unit of volume). The word "hectoliter" refers to a hundred liters, a metric unit of volume.
Think of 'hecto-' meaning 'hundred' and 'liter' as a unit of volume, so a hectoliter is simply a hundred liters.
