We want to convert 6 lbs to ounces. We assume that the pounds are avoirdupois pounds ( as opposed to metric pounds or troy weight.)

In the avoirdupois system, there are 16 ounces in a pound. (Here ounces are also assumed to be avoirdupois -- not apothecary or nutritional ounces.)

Thus we have 1 lb is 16 oz.

We can set up a proportion:

1 lb is to 16 oz as 6 lbs is to x oz or ` 1/16=6/x `

Solving for x ( the product of the means equals the product of the extremes, or simply "cross multiply") we get



There are 96 ounces in 6 pounds


We can also treat this as a linear relationship. For every pound there are 16 ounces. If the number of pounds,p, is the independent variable then, with z the number of ounces, we can write z=16p.

When doing conversions it is helpful to have a the ratios between your pounds and ounces handy.  In this case we know that there are 16 oz in 1 lb.



So when we multiply the given amount, 6 lb, we see that the units will cancel out! (the lb in the numerator cancels with the lb in the denominator)

`6 lb * (16oz)/(1lb)`

We are left with `6 * 16oz`  which equals `96 oz`

6 lb = oz. To find this, first you should know how many oz are in 1 lb. 

1 lb= 16 oz. Therefore if you multiply  `16 * 6= 96oz`

There are 96 oz in 6 lbs. You can also set up a proportion to find the answer: 


x=96 oz.

6 1b =      Oz

1 pound is equal to 16 oz therefore you will have to multiply 16 by 6 to get the answer:
6 x 16 = 96
There are 96 oz in 6 pounds.

Since there are 16 is in 1 lb you can just multiply 16by 6 which is 96.
