convertion from pounds to kilos

Hello, I am doing the subtitles for "Golden Seal" Í have a question for the following dialogue:
-You´ve got some salmon for me?
- 350 pounds.
(I converted it into kilos -158-)
But then:
- 13 cents a pound more than last time.
¿How could I translate it? Thanks for your help.

350/158*0.13=0.29 "centavos"

or you could say "350 libras" and "13 centavos"
