8lb translate Russian

We had a little carelessness here, and the other day one of our girls presented us with an 8lb American-Japanese boy.

Произошло недоразумние, и одна из наших девочек родила американо-япошечку.

That is 173.8lb, which means I have lost well over a stone.

78 килограмм, значит я похудел на 6 килограмм.
