Louis Vuitton is the best-known supplier for bags made of this leather. Epi leather is tanned with plant extracts and then dyed. The dyeing process means the leather comes in many vivid colors and is very shiny. The curing process makes the bags water resistant so they are ideal for everyday use. Avoid snagging the bag as they are sturdy, but still can be easily ripped.
The formula for calculating Miles Per Gallon is simply miles driven divided by gallons used. So to calculate the miles driven you take the miles at the end of the tank and subtract the Miles at the start of the tank, and then you divide that by the total gallons of gas used.o to calculate the miles driven you take the miles at the end of the tank and subtract the Miles at the start of the tank, and then you divide that by the total gallons of gas used.
1. Place the value in liters/100 kilometer (represented by l/100 km in the formula) that you want to convert to miles/gallon to replace the blank space below. This is based on the fact that 1l/100km = 235.214mpg (that means that if 1 liter could go 100 km then 1 gallon would go 235.214 miles).d. 2. Perform the above calculations to get the end result in miles/gallon or mpg. Note the 1/(x g/100km) represents the reciprocal of x g/100, which was found by the preceding two calculation and then inverting that with 1/x which represents a common button on calculators for reciprocal, l/100 km and miles.
