How to say 8.2 catties?

I often wonder how to say 8.2 in Teochew and today I heard how to say 8.2 catties. 

It is said as boih4 geng1 ri6 八斤二

In the video, she said geng1 differently and this is because of her accent. People with Swatow accent say geng1 for catty. 

In China 8.2 catties is equal to 4 kilogram 100 grams because 1 geng1 = 500 grams and 2/10 of 500 = 100 grams, because 8 geng1 = 4 kg and 0.2 geng1 = 100 grams. 

I find it rather offensive to think they are going to kill those chicken. I would rather be a vegetarian than to kill an animal. So for those of you who find it upsetting to think about people killing animals, then do not open the link above.
