Birthweight math or decimals are not my thing...

in Babies: 9 - 12 Months

When I write DS birthweight, I usually write 10.8lbs, meaning 10 pounds 8 ounces.  BUT there are 16 ounces in a pound, so the actual measure would be 10.5 lbs, meaning 10 lbs 8 ounces right?

 

so when I triple his birthweight it's

10 x 3

+

.5x 3

or 31.5 not

10.8 x 3 or    32. 4

 

right? 

I mean we have to do fractions math for the decimals since pounds are not a tens based system??

f*ing new math

 

Do I seem wicked dumb now?

    I think I followed that - yes, 31.5 would be right. Smile

    I never got this either when the nurses/drs did it. 10.5 is 10 1/2.



    For 10lbs 8oz you wouldn't write 10.8. That would mean something entirely different. 

     

    In your case. 10lbs 8 oz doubled would be 21lbs since 8 x 2 = 16 = 1lb.  

    I think. lol

    lol, I realized I don't do it right either.  I said he'd have to be 31lbs to triple but he was only 9'11'' at birth...so either I don't know how many ounces are in a pound or I just am not good with the fractions.

    learn metric!  The whole world does it!

     Haha, Brookie - yesterday, DD had her 6-month shots and my Dr. kept giving me her measurements in metric and I kept asking for it in lbs and inches. She was like "You're Canadian, what's your excuse?!" I don't know why but weight and height have always been easier in lbs and ft and inches for me.

    How big is Ethie now? Akhil was only 6 lbs. 8oz. so he might be able to triple his birthweight to 19.5.

    You are not dumb. DH has trouble with these things too. I spent my college years working in a supermarket so I can figure ?these things out most of the time.?
