Example B: Change 375 minutes to hours and minutes.
Solution: 375 min ÷ 60 min/hr = 6.25 hours = 6 hours 15 minutes
Example C: Convert 42 rods 5 yards to feet.
Solution: (42 rods x 16.5 ft/rod) + (3ft/yd x 5yd) = 708 ft
Counting Linear
12 units = 1 dozen (doz) 1 cubit = 18 inches = 1.5 feet
12 dozen = 1 gross (gr) 12 inches = 1 foot (ft)
144 units = 1 gross (gr) 3 feet = 1 yard (yd)
1 ream (rm) = 500 sheets 36 inches = 1 yard
300 feet = 100 yards
Time 5,280 feet = 1 mile
60 seconds (sec) = 1 minute (min) 1320 feet = 1/4 mile
60 minutes = 1 hour (hr) 440 yards = 1/4 mile
24 hours = 1 day (da) 1,760 yards = 1 mile
7 days = I week (wk) 220 feet = 1 furlong
30 days = 1 calendar month (mo) average 8 furlongs = 1 mile
4.233 weeks = 1 month 2 furlongs = 1/4 mile
7 Days = 1 Week, Surveying Lengths
4 weeks of 28 days = 1 month 25 links = 1 rod
13 four week periods + 1 day = 1 year 4 rods = 1 chain
16 1/2 feet = 1 rod
13 weeks = 1 quarter (of a year) 5.5 yards = 1 rod
52 weeks + 1 day = 1 year (yr) 320 rods = 1 mile
12 Calendar months = 1 year
360 days = 1 business year Cubic or Volume Measure
365 days = 1 year 1,728 cubic inches (cu in) = 1 cubic foot (cu ft)
366 days = 1 leap year 144 cubic inches = 1 board foot (bdft)
27 cubic feet = 1 cubic yard (cu yd) 5
128 cubic feet = 1 cord (cd) of wood
Dry Measure
2 pints (pt) = 1 quart (qt) Liquid Measure
8 quarts = 1 peck (pk) 1 cup fluid ounces (fl oz) = 8 ounces (oz)
4 pecks = 1 bushel (bu) 16 fluid ounces (fl oz) = 1 pint
1 bushel = 2,150.42 cubic inches 4 gills (gi) = 1 pint
1 bushel = 1.244 cubic feet 2 pints = 1 quart
4 quarts = 1 gallon (gal)
1 bushel of corn = 56 pounds (lbs)
1 bushel of oats = 32 pounds Volumes
1 bushel of barley = 48 pounds 231 cubic inches = 1 gallon
1 bushel of wheat = 60 pounds 1 cubic foot = 7.48 gallons
1 bushel of sorghum = 50 pounds 31.5 gallons = 1 barrel (bbl) non-oil
1 bushel of milo = 56 pounds 42 gallons of oil = 1 barrel (bbl)
1 bushel of soy beans = 60 pounds 63 gallons = 1 hogshead (Hhd)
7.48 gallons = 1 cubic foot (approx.)
Weight 1 acre ft = 43,560 square feet x 1 foot deep
16 ounces (oz) = 1 pound (lb) Surface or Square Measure
7,000 grains (gr) = 1 pound 144 square inches (sq in) = 1 square foot (sq ft)
100 pounds = 1 hundredweight (cwt) 9 square feet = 1 square yard (sq yd)
2,000 pounds = 1 ton 304 square yards = 1 square rod (sq rd)
20 hundredweight = 1 ton 160 square rods = 1 acre (A)
2,240 pounds = 1 tone (metric ton) 1 acre = 43,560 square feet
or 640 acres = 1 square mile (sq mi) or 1 section
2,240 pounds = 1 long ton 36 sections (or sq mi) = 1 township (twsp)
