If you are using paypal to implement a shopping cart and are getting this error please read on…..
You are probably trying to create shopping cart buttons for items that have weight specified in ounces.
You realized that paypal weights are specified in pounds so you specified a fraction i.e. .0625
When you try to add an item to your shopping cart you get the following error:
A weight value must be an integer greater than or equal to one
This error is quite misleading! Paypal is very fussy about the format of decimals.
To specify one ounce you must specify the weight as follows
0.06
It’s important that you have the zero before the decimal point and no more than two digits after the decimal point.
Here is a table you might find useful for ounce->pound paypal conversions
1 oz = 0.06
2 oz = 0.13
3 oz = 0.19
4 oz = 0.25
5 oz = 0.31
6 oz = 0.38
7 oz = 0.44
8 oz = 0.5
9 oz = 0.56
10 oz = 0.63
11 oz = 0.69
12 oz = 0.75
13 oz = 0.81
14 oz = 0.88
15 oz = 0.94
Be sure to type the numbers in EXACTLY as they are above.
Hope this helps all those struggling with this error message.
