1.0 is weight equals 1lb or 16 oz?

I am a little confused, I should have asked this question a long time ago.

The question pertains to both the USPS shipping weight and the overal product weight. If I add 1.0 does this mean its 1 lb (or 16 oz)? Another words 2.0 is 2lbs or 32oz? Or is 1.0 equal a gram?

Just want to double check before changing my shipping settings.

The way I have it set now is converted to decimal like this chart: http://support.mightymerchant.com/home/mm4/page_1048/ounces_to_decimal_conversion_chart.html

I just want to double check this method is correct.

that's how we do it. for us, it's easy because we sell in troy ounces & a troy ounce is 1/10 pound for our purposes.

Zen Cart works in decimals. But you're the one who decides whether you're using lbs or kgs. So if 1.0 for you is 1 lb then any fraction of that would be entered into ZC as its decimal equivalent.
Some carriers ONLY support lbs, such as USPS, so that pretty much forces you to be using lbs for everything in your store. Thus, something like the chart you referred to is a correct representation.

My primary concern is the store returning accurate shipping rates and I use USPS. So I wanted to make sure the weight in the product view and attributes was accurate according to USPS weight specifications. If I were to use the weight field as grams and USPS uses this field as lbs, well then, I would get an inaccurate shipping rate (especially with multiple products).

In the past I have built all the stores using the decimals conversion, but for some reason one of my stores shipping rates were off a little so I thought maybe it was the weight settings per item. Turned out to be the settings in the USPS module which I have adjusted.

Since it has been such a long time that I checked into this, I was a little hazy and though I had better check it out again just to make sure.

You have confirmed my original assessment. Thank you for your time and help.
