English to Hebrew Bus/Financial Livestock / Animal Husbandry מידת משקל

"...The price in his area is typically $X under the XXXXX XXX XXX futures price, which is currently trading at $XX *per hundredweight*...

I'm familiar with the differences between UK/US hundredweight (app. 50/45 Kg). The question is if there is an Hebrew equivalent, other than "ק"ג לערך 50"

Thanks!
