WEIGHT
WEIGHT 1 oz. = 28.35 grams
1 lb. = 0.453592 kilograms
= 0.009 cwt.
1 kg. = 2.20462 lb.
= 0.01 quintal
1 cwt = 112 lb.
= 50.802 kg.
1 metric ton = 0.98421 long ton or English ton
= 1.10231 short ton
= 2,204.6 lb
1 English ton = 1.01605 metric tons
or long ton = 1.12 short tons
1 short ton = 0.907186 metric ton
= 0.892857 long ton
= 2,000 lb.
* These conversions are based on the assumption that all weights are weights in air, which is the correct
basis for computing bulk commercial quantities of petroleum.
PRICE 1 US cent/AG = 0.42 US$/BBL
1 US$/BBL = 0.163 Baht/Liters

POWER AND HEAT UNITS
1 HP (UK Horsepower) = 550 foot pounds per second
= 0.7457 kilowatt
= 1.014 PS (or Cheval Vapeur)
1 PS (Pferdestaerke) = 542 foot pounds per second
or CV (Cheval Vapeur) = 0.986 hp
= 0.736 kW
1 kW (Kilowatt) = 1,000 watts
= 1,340 hp
= 1.359 PS or CV
= 737 foot pounds per second
1 foot pound per second = 0.00136 kilowatt
= 0.00182 hp
= 0.00184 PS or CV
1000 Btu = 0.293 kWh
100,000 Btu = 1 therm
1 calorie (dieticians') = 4.1855 kilojoules
1 Therm = 100,000 Btu (British Thermal Units)
= 25,200 kilocalories
= 25.2 thermies
= 29.3 kilowatt hours
1000 kilocalories = 3,968 Btu
(Large Calories) = 1.163 kilowatt hours
= 1 thermie
1 kilowatt hour = 3,411 Btu
= 1.340 hp hours
= 859.6 kilocalories
LIQUEFIED METHANE
1 Ton of Liquefied = approximately 16 barrels
Methane = approximately 50,000 cubic feet
(1400 cubic meters) of natural gas,
depending on methane content
