Questions and answers on how to convert things from one unit or system to another
Forum rules
Dear 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 FaceBook page

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

You can find many of your answers by visiting But I will help as much as I can.

1) Converting miles into kilometers:
1 mile equals 1.60934400579467 kilometers so multiply the number of miles you are trying to convert by 1.60934400579467 and you have the equivalent in kilometers.

2a) Converting pounds in grams:
There are 453.592374495299 grams in 1 pound so multiply the number of pounds you are trying to convert by 453.592374495299 and you have the equivalent in grams.

2b) Converting pounds to kilograms:
There are 0.453592374495299 kilograms in 1 pound so multiply the number of pounds you are trying to convert by 0.453592374495299 and you have the equivalent in kilograms.

3) Converting gallons to liters:
There are 3.78541181779072 liters in 1 gallon so multiply the number of gallons you are trying to convert by 3.78541181779072 and you will have the equivalent in liters.

4) 20 miles / gallon = __ kilometers / liter
Our constants are: 1 mile = 1.60934400579467 kilometers and 1 gallon = 3.78541181779072 liters. Plugging those into our desired input gives us:

20 miles / gallon multiplied by 1.60934400579467 kilometers / mile multipled by 1 gallon / 3.78541181779072 = 8.502874 kilometers / liter
