Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Albert bought 14 gallons of gas that is sold for 108.5 cents per liter. How much did he spend on gas?

First, convert gallons to liters, then multiply by cost/liter ($1.085)

There is 3.7854 liters in 1 gallon

Using Dirtman's reply, take: $1.085 per liter x 3.8754 liters per gallon = $4.1072 cost per gallon

$4.1072 per gallon x 14 gallons - or about $57.50 cost for 14 gallons.

Here in Salem, Oregon, USA I just gassed up with Regular gas @ $2.939 per gallon on Friday.
