# 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)

## 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.
