Measurements
Conversion Factors1
Weight (GB & US)
- 1 English or long ton = 2,240 pounds (lb) = 1.12 American or short tons = 1.01605 tonnes or metric tonnes (or metric tons in the USA) = 1016.05 kilograms (kg)
- 1 American or short ton = 2000 pounds (lb) = 0.892857 English or long tons = 0.90718 tonnes or metric tonnes (or metric tons in the USA)
- 1 tonne or metric tonne (or metric ton in the USA) = 1000 kilograms = 2204.621 pounds (lb) = 0.98421 English or long ton = 1.10231 American or short tons
- 1 stone = 14 pounds (lb) = 6.356 kilograms
- 1 pounds (lb) = 16 ounces = 0.454 kilogram
- 1 ounce = 28.35 grams
- 1 gram = 0.035 ounce
- 1 kilogram = 1000 grams = 2.205 pounds (lb)
Length (GB & US)
- 1 league = 3 miles = 4.828 kilometres
- 1 mile = 8 furlongs = 1,760 yards = 1.609 kilometres
- 1 furlong = 220 yards = 201.17 metres
- 1 yard = 3 feet = 0.914 metre
- 1 foot = 12 inches = 30.48 centimetres
- 1 inch = 2.54 centimetres
- 1 kilometre = 0.621 mile
- 1 metre = 1.094 yards = 3.281 feet
- 1 centimetre = 0.394 inch = 0.033 foot
-
1 millimetre = 0.0394 inchPage 714
- 1 nautical mile = 1.852 kilometres
Volume (GB & US)
- 1 cubic foot = 1,728 cubic inches = 0.028 cubic metre
- 1 cubic metre = 35.315 cubic feet
- 1 cubic inch = 16.387 cubic centimetres
- 1 cubic centimetre = 0.061 cubic inch
Liquid Volume (GB & US)
- 1 imperial gallon (GB) = 8 imperial pints = 4.546 litres
- 1 US gallon = 8 US pints = 3.785 litres
- 1 litre = 0.220 imperial gallons = 0.264 US gallons
- 1 oil barrel (bbl) = 42 US gallons = 159 litres = 35 imperial gallons
- 1 tonne = between 6 and 8 barrels (bbl) depending on density of the petroleum variety
Stowage Factors2
The stowage factor of any commodity is the figure which expresses the number of cubic metres per tonne (metric) or cubic feet per ton of 2,240 lb, which will occupy in stowage and should include a proper allowance for broken stowage and dunnage. On the other hand, liquids fill the tank into which they are put. For this reason the number of tonnes (metric) per cubic metre (specific gravity) for the temperatures of the liquid is considered in preference to the stowage factor.
