Description
The miles per gallon gasoline equivalent is based on the energy content of gasoline. The energy obtainable from burning one US gallon is 115,000 BTU (34 kWh). Thus one mile per gallon gasoline equivalent is equal to 115,000 BTU per mile. For alternative fuels, energy required to manufacture the fuel may also be considered. For electrical power, the energy of any fuels used to generate the electricity and the transmission efficiency must be considered.
To convert the mile per gallon rating into other units of distance per unit energy used, the mile per gallon value can be multiplied by one of the following factors to obtain other units:
-
1 MPGe = 8.55 miles/ million BTU ≈ 0.0292 miles/kW·h ≈ 0.0182 km/kW·h ≈ 0.005 km/MJ

Famous quotes containing the word description:
“A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
—John Locke (1632–1704)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
