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.

How many pounds in a gallon

Postby Anjie » Thu Jul 19, 2007 9:20 pm

A gallon is 128 oz

4 qt (32 oz) = 1 gallon

16 oz = 1 lb

128/16 = 8 lbs

You should differentiate between fluid ounces and ounces avoirdupois.

The anwer is

First convert US(Gallaons) into liters

1 US(Gallon) = 3.785 lit.=0.003785m3

Now what is the component e.g its is Water

so at STP Water density is 1gm/cm3 or 1000kg/m3

so multiply m3 * Density you will get mass

3.785m3*1000kg/m3 =3.785kg

now convert kg into pounds (US)

1 kg = 2.2046 lb
so 3.785 kg = 8.3445lbs(US).

if you are satisfied from the solution email me.
