Before electronic calculators, converting square varas (at 1 vara = 32.8748 inches) to acres was a tedious job. But if 1 vara = 33 1/3 inches, 3 varas are exactly 100 inches, 36 varas are exactly 100 feet, and 108 varas are exactly 100 yards. An easy division and some shuffling of the decimal point do the job.
Motorhomes and travel trailers are typically 7-1/2' to 8-1/2' wide. The mirrors on both sides of a motor home will add another 1-1/2 feet or so, for a total width of approximately ten feet on the largest ones. The overall height for a motorhome or camper with a roof-mount AC unit can be 13-1/2 feet or a little more.
