Question

How to convert 147.9 price per liter to price per gallon 

Answer 1

Let's find the conversion between the two.
1 liter : 0.264 gallon.
We need to multiply 147.9 by 0.264 to find the number of gallons.
147.9×0.264172
39.071039
We need to round to two decimal places since it's money.
39.07
So, $147.9 per liter = $39.07 per gallon.
But, I'm not sure if you may round the conversions or not, because some may just convert it to 2 decimal places or even a whole number.

Answer 2

Qn: Price/liter to Price/gallon

Now,
1 liter = 0.2642 gallons

Therefore,
Price per gallon: 147.9/l = 147.9/ (1*0.2642) gallons = 147.9/0.2642 gallons = 559.80/gallon
