Conversions, Part 2

This section covers additional, sometimes obscure, unit conversions that have appeared on recent exams.

• 1 sq. mile = 640 acres
• 1 bushel = 4 pecks
• 1 mile = 320 rods
• 1 day = 1440 minutes
• 1 rod = 16.5 feet

Knowing that 1 mile = 320 rods allows for quick calculations of feet in fractional parts of a mile. For example, since $16.5 = 33/2$, 1 mile = $320 \times 16.5 = 160 \times 33$ feet.
