In the UK, a significant proportion of children have not only experienced drinking alcohol by the time they are allowed to purchase an alcoholic beverage (i.e. before 18 years of age), but are likely to have been drunk at least once in the last 4 weeks.

A Btu (British Thermal Unit) is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit. Table 1 shows the Btu value for various energies. To compare the values on a propane equivalent we first convert the values to a MMBtu (1 million Btuâs). You take the energyâs price and divide it by its MMBtuâs. Natural gas is priced on a MMBtu basis. We then multiply the amount of propane Btu content per MMBtu (.0915) to get the propane equivalent value.
