Cumulus
The Kumme is an old, rather coarse and not very precise, Prussian volume measure for field and paving stones . Then designated
- in Berlin 1 cumulus = 24 cubic feet (6 feet long and 4 feet wide, 1 foot high)
- 5 kummen = 120 cubic feet (1 cubic rod ) broken stones = 6 kummen unbeaten stones
- in other Prussian provinces 1 cumulus = ⅛ cubic rod = 27 cubic feet (according to Mendelssohn, however, 24 cubic feet)
According to other sources, a pile of stones measuring 8 feet or 96 inches long, 18 inches wide and 15 inches high was reckoned to be
- 1 cumulative = 15 cubic feet = 14.4309 Parisian cubic feet = 0.4946 cubic meters
In addition, 6 kums of broken stones counted as 5 kums (without spaces) of packed stones. 5 totals of 24 cubic feet each gave 120 cubic feet. This volume of 1 cum = 24 cubic feet measured 9 feet long, 4 feet wide, and 1 foot high , considering the loose bed (the lot factor ).
