1 kilogram (kg) = 2.2 pounds (lb) = 1000 g
1 lb = 454 g = .454 kg = 16 oz
kg x 2.25 = kg
lb x 0.454 = kg
1 oz = 28.349 g
1 g = 1000 mg
oz = 28.349 = g
g x 0.935 = oz
Liquids1 oz = 30 milliliters (ml)

0Mar 21, '13 by Baubo516, ADN, RNI'm with Don1984  I don't like it when they use 1 qt = 1,000 mL, but that's the equivalent that makes the 2nd problem work.

2Mar 22, '13 by morteEm! Esme was taking responsibility for her perceived error. Have you sorted the issue of your book out now? I would like to know the name of the book, that way if we run into this issue here at AN again we can "solve" it much more quickly!Quote from EmilyEmilyI dont need any pity.

1Mar 22, '13 by Esme12, ASN, BSN, RN Senior ModeratorQuote from EmilyEmilyUhm....no honey, I wasn't giving pity.....I gave different information confusing the situation even more. morte pointed it out to me. My goal is only to help. I never judge (well seldom judge) and I am always fair(always).I dont need any pity. Just looking for a bit of help and clarification
I agree with Morte what is the name of the book so we can know how to help, and not further confuse, in the future.EmilyEmily likes this. 
0Mar 22, '13 by ♪♫ in my ♥It's every bit as absurd to say that 1 pint = 500 mL as it would be to say that pi = 3
So now 1 gallon = 4 liters? 
0Mar 24, '13 by nurseprnRNIntake and output is not math, it's arithmetic. No matter what the liquid is, you add the number of cc that went in (Intake, I) and the number of cc that came out (Output, O). That's pretty much it.
If they want to know what the balance is, that means that you lok at the difference between intake and output.
If there was more intake than output, the patient is in positive fluid balance (positive here is not necessarily a good thing it means a positive number, greater than zero). Do the subtraction.
If output was greater than intake, that's a negative fluid balance (negative is sometimes a very good thing indeed, if someone was fluidoverloaded in the first place and you want him to pee out more than he takes in). Do the subtraction.
Does this make it clearer for you?
