The price of fuel in Mexico has increased as follows:
Magna, up 8.2% to 8.44 pesos/liter = $2.51 per gallon (peso at 12.72 per U.S. dollar on 14 August 2010)
Premium, up 3.9% to 9.94 pesos/liter = $2.96 per gallon
Diesel, up 7.8% to 8.80 pesos/liter = $2.62 per gallon
To calculate fuel prices I used the following formula:
divide 3.785 (liters) by today’s peso exchange rate (example: 12.72) and multiply this by the current price-per-liter (example: 8.44 pesos for Magna) to get: $2.51 per gallon.
In other words: 3.785 divided by peso rate, then multiplied by price per liter.
Here’s another method, excerpted from the Driving chapter in the 13th edition of our book, The People’s Guide To Mexico.
Those of us who are easily boggled when trying to convert pesos-per-liter into dollars-per-gallon will rejoice at Codo’s Conversion.This relatively simple formula was suggested by David Eidell, an engineer and skilled number cruncher who is aptly nicknamed “El Codo” (Cheapskate). Using a small pocket calculator, David teaches math-challenged travelers how to quickly convert our metric gas purchases into familiar dollar-per-gallon amounts. Here’s how it works:
1. Turn on your calculator and enter the price of a liter of gasoline (shown on the pump).
2. Multiply the price by 4.
3. Multiply this result by 94.64 percent and. . .
4. Divide the result of Step 3 by the current peso/dollar exchange rate to get the price, in dollars, of one gallon of gasoline.
Here’s an example:
1. The price of gas is 6.0 pesos per liter.
2. 6 x 4 = 24
3. 24 x .9464 (94.64%) = 22.713
4. 22.713 ÷ 9.6 (9.6 pesos to $1) = $2.37
By the way, this same formula will also convert propane prices to dollars-per-gallon. When calculating propane by weight, however, allow two kilos per gallon.
