It's a Girl!

Congratulations to my sister and brother-in-law on their new addition, Quincy Greenfield Bartlett, born in Texas on November 10 at about 9:00 PM local time (10:00 PM Eastern Time).

Trivia question for the day: Which is heavier, my niece-- born 6 pounds, 12 ounces-- or 8 pounds of gold? I'll post the answer tomorrow (no points unless you explain why).

Your niece weighs more, because of the concepts of "troy ounces" and "troy pounds". The troy ounce is smaller than the avoidupois ounce, and the troy pound is considerably smaller than an avoidupois pound.

Your niece weighs 3048.143 grams (avoidupois ounce=31.1035 grams, avoidupois pound=16 avoidupois ounces). 8 pounds of gold weighs 2721.6 grams (troy ounce=28.35 grams, troy pound=12 troy ounces.)

Yes, I can be quite anal-retentive; why do you ask? (grin)

Bingo-- almost. The troy ounce is actually a bit heavier than the avoirdupois ounce, though not so much heavier that 12 troy ounces (one troy pound) is as heavy as 16 avdp. ounces (1 avdp. pound). Hence, as noted here, "an ounce of gold weighs more than an ounce of feathers, but a pound of gold weighs less than a pound of feathers." "Baby-fat" may of course be substitued for "feathers."
