U.S. customary units for dry measures: 1 bushel = 4 pecks = 32 dry quarts = 64 dry pints = 35.23907016688 liters = 2150.42 inch3.

1.136...

1 quart = 1.13625 l (liters).

British imperial units for dry and liquid measures: 1 bushel = 4 pecks = 8 gallons = 32 quarts = 64 pints = 256 gills = 1280 fluidounces = 36.368736 liters.

U.S. customary units for liquid measures: 1 gallon = 4 quarts = 8 pints = 32 gills = 128 fluid ounces = 1024 fluid drams = 61440 minims = 3.785411784 liters = 231 inch3 (cubic inches) & 1 (British imperial) gallon = 4.54609 liters = 1.201 (U.S.) gallons = 277.42 inch3.

1 ell = 1.25 yards = 3.75 feet = 45 inches = 60 digits = 1143 mm.

1 bolt (fabric) = 32 ells = 40 yards = 1440 inches = 36576 mm.

1.3595

The standard atmospheric pressure at sea level is 1 atm (atmosphere) = 1,013.25 millibars = 29.921 inches of mercury (inHg).

Units for pressure measures:

1 atm (atmosphere) = 1013.25 millibars = 101,325 N/m2 (pascals) = 1033.227 g/cm2 = 10,332.27 kg/m2 = 760 mmHg (torrs) = 29.921 inHg = 14.696 lb/inch2 (psi) &

1 bar = 105 N/m2 (pascals) = 106 dynes/cm2 (cgs bars).

1 mmHg (torr) = 133.322 N/m2 (pascals) = 1.3595 g/cm2.
