Measures and weights
1. Linear measures
1 inch (in) = 2,54 cm
1 foot (ft) = 12 inches = 30,48 cm
1 yard (yd) = 3 feet = 91,44 cm
1 furlong (fur) = 220 yards = 201,17 m
1 mile (m) = 1760 yards = 1.609 km
1 league = 3 miles = 4,828 km
2. Nautical measures
1 fathom = 6 feet = 1,829 m
1 cable = 608 feet = 185,31 m
1 nautical, sea mile = 10 cables =1,852 km
1 sea league = 3 nautical miles = 5,550 km
3. Liquid measures of capacity (BRITISH)
1 gill = 0,142 l 1 pint (pt) = 4 gills 0,568 l
1 quart (qt) = 2 pints 1,136 l
1 gallon (gal) = 4 quarts 4,564 l
1 barrel = 35 gallons = 159,106 l
1 barrel = 36 gallons (Bier) = 163,656 l
4. Liquid measures of capacity (American)
1 gill 0,118 l 1 pint = 4 gills = 0,473 l
1 quart = 2 pints =0,946 l
1 gallon = 4 quarts = 3,785 l
1 barrel = 42 gallons = 159,106 l
5. Avoirdupois weights
1 grain (gr) = 0,065 g
1 dram (dr) = 27,3438 grains = 1,772 g
1 ounce (oz) = 16 drams = 28,35 g
1 pound (lb) = 16 ounces = 453,59 g
1 stone = 14 pounds = 6,348 kg
1 quarter = 28 pounds = 12,701 kg
1 hundredweight (cwt) = 112 pounds (Brit) = 50,8 kg = 100 pounds (US) = 45,36 kg
1 ton = 20 cwt (Brit) = 1016 kg = 2000 pounds (US) = 907,185 kg
